Even in GC when she said she no longer wanted to pursue medicine, it was in a state of grief and depression. After losing her father she had no will to live, let alone study.
Virat locks her because he wanted her to attend some function at home and she wants to go to college to talk to the dean. He doesn't find out about her intention to leave the city until much later in KD.
In KD we see how dedicated Sai is to her goal. Eventually after all the MU, basically Sai is essentially seen devoting herself entirely to medicine and service. In KD when she finally separates from virat for 5 years and when they eventually meet its at the prize ceremony where Sai is being awarded for her service to the community as a doctor.
Sai does care a LOT about her education, the dream of becoming a doctor is both hers and her father's. Sadly her life in CN keeps in interfering with her headspace in such a toxic and negative way that she is depressed and suicidal. In KD she says she has lost the will to live because of how badly everyone treats her.
It'll be unfortunate if the makers trivialize this matter.
Its also unfortunate to see how people misinterpret and misquote things.
