A professional is by definition someone who makes money by doing that thing.
Maybe some 2500s bum around and win local tournaments, sleeping on people's sofas, in vans, or whatever.
But for a professional chess player to afford things like a house and car, maybe 20 people in the world can do that by playing, and they're all over 2700. Then maybe a few 100 can make money by coaching and writing books, and that's a random assortment of titled players, mostly GMs.
Ok. I guess I won't be one of those.
