Going back to the original question...
Probably, in that regard, yes. I really don't know... I mean if you are a very talented person and you can prove that you are a good music composer, then going to a university wouldn't necessarily be needed. But normally, I think that the answer to that question would be yes.
In other areas in the music industry, college isn't required. Being a pop or rockstar or even being a session musician and even a songwriter doesn't require college at all. You can still go to a university or something, but if you already have enough knowledge in whatever you are planning to do (sessions, engineering, solo artist, etc.), then college/a university isn't really needed.
