Is it okay to not have interest in formal study

I am currently in india doing a under graduation degree . Its my first year .But i am really not into this i don’t like to learn all this bullshit although i got 90%in 12 examination. But still i like to learn about business and planning to start one . I have recently watch a short video saying maximum billionaire and millionaire have college degree. So if i am not interested in this am i missing something. I am really confused right now .so please provide any suggestions you have
