Most colleges are "bottom feeder colleges" no? You have to take the average college. What I mean is in the sense that even if you have only 3-4 hours of lectures per day, you're not doing it back to back so you're spending 6ish hours atleast on campus, and you're doing it every day. I am aware of how intensive(or lack thereof) the other degrees are, but it's time burned on campus regardless.
not going to comment on the work ethic of passion professions, although I will agree it's never given priority from the top down.
the cracked players that can make it in high school will already be making waves in the vcl qualifiers/directly qualifying to VCL. The point is the vast majority of players don't make it. Collegiate is a system that can sustain them. Collegiate esports is the future, look at the way it's setup in NA(likely will never get to this point in India unfortunately). Not sure on how EMEA does it. The reason it works is that if you join college after school, your first two years of uni are relatively stable, you can find time to compete(18-20).
