There's a difference between being a pro and playing at a level the masses would consider "pro speed".
A pro would just be an individual:
"engaged in a specified activity as one's main paid occupation rather than as a pastime"
A player's fargo rating is moot.
Consider that a player could earn their revenue from sponsorship rather than results from competition. So you can be a "professional" by definition and be a terrible player. On the flip side you could play pool as a pastime activity and play what the masses would consider "pro speed".
My point... We need to come to terms with player ability not being a matrix to dictate whether or not that player is a "pro".
Golf has long ago come to the realization that there are two different types of "pro".
The club/teaching pro and the playing pro.
The club pro is an industry professional who manages golf courses, runs tournaments, and may or may not give lessons. They're knowledgeable and skilled at management and have at least a minimum ability to play the game, but some of them struggle to break 80 on a consistent basis.
The playing pro does just that. They play for a living. The best of the best we watch play on Sunday afternoon on TV, but there are thousands more playing in small tours around the country. As a population they tend to get around the golf course pretty well but they aren't in the same
universe as the guys who play for real money on the big tours. The difference between a true touring pro and a casual pro.
I'd argue that pool is similar. There are full-time league operators, tournament directors, room managers, and even instructors that are industry professionals in that that's how they make their living. Some play at a high level while others define the term banger.
They're completely different from what most of us think when we think about those pros that play "pro speed" and earn their living playing the game. The SVB's, Fillers, and Gorsts of the world. For that group I think that it's reasonable to recognize that a certain playing ability has to be there in order to be recognized as such. If you can't crack the top 100 in the United States, let alone in the world, you probably aren't at that level, no matter how many tournaments you play.
A quick look at Fargo puts that number at 725 for men, and honestly, once you get much outside of the top 100 in the world, 775ish, you're probably more of that "casual pro" who makes a little bit of money regionally, but isn't earning a living off his play.
The rest of us are just spending money to do something we enjoy doing, even if once in a blue moon we get a few crumbs thrown back at us when we cash in a tournament.
