Whilst continuing her professional projects, Sioux studied American Literature and Culture at the University of California (UCLA), graduating in 2024.

Career Aged nine, Sioux was cast alongside her mother on the Lifetime reality television series Dance Moms. Her parents were hesitant for her to appear on the series since they worked full-time and were caring for three children. They also did not believe Dance Moms would amount to much and liked to stay away from drama. Sioux pursued music alongside dance whilst appearing on the series, notably releasing singles including "Star in Your Own Life" and "Slay", the latter of which featured Coco Jones.

In 2016, Sioux appeared as a dancer in the off-Broadway production Trip of Love. Following leaving Dance Moms in 2017, Sioux joined the cast of the CBS soap opera The Bold and the Beautiful.

In 2024, Sioux appeared in a string of films including musical Mean Girls, The Lies I Tell Myself and thriller The Lady of the Lake: The Legend of Lake Ronkonkoma, as well as starring in Saving Nora, a miniseries. Also in 2024, Sioux published a memoir titled Bottom of the Pyramid, which she wrote whilst in her junior year at UCLA. The memoir details her experiences on Dance Moms, particularly with Miller, with whom she alleges she had various racist encounters. She then appeared as a dancer in Shuffle of Love: A Descendants Short Story (2025). 2026 saw Sioux return to the stage in the off-Broadway production of 11 to Midnight. Later that year, she appeared in a featured ensemble role in Mean Girls at Pittsburgh Civic Light Opera, having previously appeared in the 2024 film.
