I've done the US university dorm living. I was already pretty well socialized being involved in many social causes and clubs. Unlike the movies, my roommate and I didn't turn into lifelong friends. Our living arrangement was strictly business. Now, I am lifelong friends with my apartment roommates. We shared a house together but did not share a room.
Also, campus ties you closer to home more than you imagine. They shutdown campus for different breaks and you're more or less forced to go elsewhere, which is typically your family home.
But honestly, double and triple occupancy rooms are completely unnecessary and uniquely American.

It depends entirely on the person. I had a similar thing happen to me, except that I managed to get a single my first couple years of school. But I know from others, that it often creates a very intimate, fraternal bond which gives kids some semblance of a family bond before they are able to get a real social life, join clubs, make friends, find a partner etc.
