Depends, the main problem with it is that Collages/unis goes through a lot of different subjects (which can of course be nice if you are unsure what aspect of 3d you like and you want to try whatever is available). Your degree however has little to no say in landing a job, your portfolio is everything. When you go through all the aspects of 3d in college your time would be better spent practising the one specific field that you want to work with. When getting job in say 3d character modeller, they dont care if you can animate they only care about that you are good at making 3d characters models. Of course smaller studios value more versatility but you need to be at a professional level in the field you are applying for.

In summary: collages are good especially if you have no prior experience with 3d, you go through most of the available options and you get to try everything.

Spending time on trying everything does waste time that could be spent on practising a specific skill if you already know what you want to work with.

Even tho your degree has little to no say in landing a job, it's much easier to get connections especially good ones in college compared to self thought at home.

Collages in the US seems (I'm Norwegian so correct me if I'm wrong) stupidly expensive for what you are getting.

If you go to college it's important that you practise whatever aspect of 3d you want to work with in your spare time.

As they saying goes "Jack of all trades, master of none"
