Diyas mostly played on the ITF Circuit until 2014, her breakthrough season. Having started the year outside the top 150, she progressed into the top 40 by September, allowing her to enter tournaments on the WTA Tour more consistently, although she still plays ITF tournaments. She is one of the most successful female tennis players representing Kazakhstan, along with Elena Rybakina and Yulia Putintseva.
Diyas became a member of the Kazakhstan Fed Cup team in 2011 and has played for 10 years, second only to Yulia Putintseva.
In June 2008, she made her debut at the French Open, recording her first match-win at a Grand Slam tournament over Irina-Camelia Begu, before she was defeated by Lykina in the second round. She also made her doubles major debut there, losing in the first round. Diyas then reached the second round at Wimbledon. On her debut at the 2008 US Open and the 2009 Australian Open, she was eliminated in the first round. In June 2009, she played the French Open, her final junior tournament in both singles and doubles, where she reached the third round in singles, and lost in the first round in doubles.
At her first two appearances in 2009, she reached a quarterfinal before winning another ITF title at the $25k event in Stuttgart. She then made her WTA Tour singles debut at Prague as a wildcard player, where she marked her first WTA Tour win and first quarterfinal. She defeated qualifier Kristina Mladenovic and sixth seed Petra Kvitová but later was eliminated by third-seeded Iveta Benešová. The year of 2009 was important for Diyas, as she made her first appearance at a major tournament in qualifying at the US Open, although she lost to Chang Kai-chen in the first round of qualifying.
In late 2011, Diyas underwent shoulder surgery and did not play tennis for the next seven months, causing her to fall in the rankings to outside the top 300. In May of the following year, she made her return on the ITF Circuit at the Kangaroo Cup where she failed to qualify for the main draw. A month later, she won her third ITF title at the $25k event in Bukhara, without dropping a set during the entire tournament. Later that year, she was advanced to the final of a $25k event in Taipei, where she lost to Zheng Saisai. The next week, she participated in a new WTA Challenger event, also in Taipei. In the first round, she defeated the world No. 40 and top seed, Peng Shuai, in straight sets.

Diyas then went to Europe but lost early in the first two tournaments contested. At Strasbourg, she returned to form with a first-round win over world No. 22, Kirsten Flipkens. She followed it up by dispatching Ajla Tomljanović before having to retire in her quarterfinal match against Christina McHale during the second set. Holding a world ranking of No. 86, Diyas was granted a spot in the main draw of the French Open but a difficult draw saw her knocked out by fourth seed Petra Kvitová in the first round. At the ITF grass-court tournament Nottingham Trophy, she advanced to the final but was narrowly beaten by Kristýna Plíšková. She played one more grass-court event at the before entering Wimbledon, at the Birmingham Classic, where she was eliminated by CoCo Vandeweghe in the first round. She record her first ever Wimbledon victory by defeating Kristina Mladenovic in a rain-delayed straight-sets match. Diyas then recorded three-set wins against 15th seed Carla Suárez Navarro and 2010 Wimbledon finalist Vera Zvonareva, before losing in straight sets to third seed Simona Halep in the fourth round.
In late July, she returned to the United States to compete at the Washington Open, where she reached the second round. Then, at the Cincinnati Open, she advanced to another second round, losing there to Lucie Šafářová.
Then, in her best result at the US Open to date, the unseeded Diyas advanced to the women's singles third round where she lost in straight sets to 17th seed Ekaterina Makarova, earning $105,090. There, she also played in the doubles event, where reached her first Grand Slam quarterfinal alongside Xu Yifan.

At the Miami Open, she also got a bye but lost in the second round to CiCi Bellis.
The clay-court season didn't start well for Diyas, as she lost in first round of the Charleston Open. Diyas followed up this performance by making double-bagel against Sabine Lisicki in the first round of the Premier-level Stuttgart Open but later did not make it to the quarterfinal, losing to Sara Errani. Her next step was Premier Mandatory Madrid Open, where she lost in round one to Carla Suárez Navarro.

Diyas, however, reached the round of 16 at Birmingham by defeating Kateryna Bondarenko in straight sets and through the withdrawal of Victoria Azarenka.

She beat 24th seed Flavia Pennetta, qualifier Aliaksandra Sasnovich and 14th seed Andrea Petkovic. However, her stealthy run at Wimbledon was ended by the fourth seed Sharapova.

She went on to score victories against several higher-ranked players, namely local favourite Misaki Doi, top 30 player Zhang Shuai, compatriot Yulia Putintseva and defending champion Christina McHale. In the final, she beat fellow qualifier Miyu Kato to win her first ever WTA title.
In May, she reached the quarterfinals of a WTA Tour clay-court event for the first time in her career at Strasbourg, losing in straight sets to the eventual champion Anastasia Pavlyuchenkova.

Diyas received a main draw wildcard for the 2026 Australian Open.
Diyas did not play any match for Kazakhstan from 2012 to 2014. During that time, Kazakhstan remained in Zone Group I. They had a chance to be promoted to World Group II in 2014 but lost the World Group II play-off in 2013 to France. On her return in 2015, Diyas won all of her three singles matches. That was enough for Kazakhstan to win their round-robin group; however, they later lost to Japan in the playoff, missing another chance to get to the World Group II playoff. The next year, Diyas only played singles matches and was victorious in both of them, but it was not enough for Kazakhstan to win their round-robin group. Later they played against India for 5th place in Zone Group I, but didn not win the tie. After one year of absence, Diyas not only returned to play at Fed Cup, but also played her first doubles match there since her debut in 2009. Kazakhstan was the winner of their round-robin group, where Diyas won all her five matches, three in singles and two in doubles. Nonetheless, in the playoff of Zone Group, they lost against Japan and missed their chance to play in the World Group II playoff to potentially get to the World Group II in 2019.
The 2019 Fed Cup was important for Diyas, being the first year when Kazakhstan advanced out of the Zone Group with Diyas as part of the team. In the World Group II playoff, Kazakhstan faced Great Britain. Diyas lost both of her singles matches, against Johanna Konta and Katie Boulter, despite winning the first set of both matches. In 2020, format of the Fed Cup changed, allowing Kazakhstan to be a part of the 2020 Fed Cup qualifying round. Kazakhstan played against Belgium for their place in the Finals round but lost 1–3. Diyas had two singles match losses against Kirsten Flipkens and Elise Mertens. Due to the COVID-19 pandemic, the 2020 Fed Cup was forced to be split into two years, so that the 2020 Fed Cup Finals round was postponed to 2021, when it was renamed the Billie Jean King Cup.
As a junior, Diyas was coached by Jaroslav Jandus when she was seventeen years old. After undergoing shoulder surgery in late 2011, she started working with Alan Ma in Guangzhou. In 2018, she split with Ma and started a collaboration with two Italians, Roberto Antonini as her coach and Carlo Bilardo as her athletic trainer. Dunlop Sport sponsors Diyas, providing her racquets, clothing and shoes. She uses the Dunlop Srixon Revo CV 3.0 Tennis Racquet.
In 2019, she won the Fed Cup Heart Award for the Asia/Oceania Zone Group I. She is the third player from Kazakhstan to win that award, and hers was the fourth won by a Kazakhstan national. In 2014, she was nominated for Newcomer of the Year but lost to Belinda Bencic.
