Can only speak from personal experience (and friends and people I studied with, of course) but yes, it used to be pretty common (I graduated in 2010) to simply study in the town you grew up and live at home until you're done. Even with 5 year degrees, so until 25. Of course with a little financial support you could also get a small apartment or share one. And a lot of universities have dorms, even when they're not campus universities, then you might be living 5-15 km away from most of your classes.
