I think a lot of low round count guns being sold is due to just not being a fit to the shooter. It can also be due to some people just trading guns. They buy, shoot a little, then move on to something else. I have a lot of things I've barely shot in my collection. Most of my guns are under 200 rounds each, but the ones I shoot I shoot a lot. My carry gun has a few thousand through it. My competition gun has several thousand. Plus, if you look at most guns you can see the difference between 200 rounds and 2000 rounds.
