Successful professional musicians almost always have to make a career from many parts - performance, session work, teaching, their own creative work or band, etc. Few artists of any sort are lucky enough to strike it rich and end up a top tier touring and recording act.
So skills like being able to put together a band that can play weddings, or being able to sit down and play from music instantly are essential. So is being able to write music. A lot of the key skills can be learned from private teachers, but if you can afford it study at a college like Berklee will really accelerate the process.

Private study means you can eat, too!
Seriously, for performance study, not a great idea.
The real benefit from places like that come when you are qualified to graduate when you apply. NETWORK.
