She is 16. I don't know what her income has to do with it. But anyway I disagree.
Income is precisely the difference between pro and amateur. That said, the distinction in all sports has been reduced/ diminished in recent years in all sports. In pool there really has never been one. Old school rules you take a dime in prize money you are a pro. All pool tournaments pay cash. So if you win $40 in a $5 weekly, you are a professional in the old school strict sense. Pool hasn’t done it that way, and maybe for sensible reasons.
The rules in other sports have loosened over the years, and now with college N.I.L. money we see a decrease in hypocrisy but an increase in professionalism. I basically don’t care regarding pool or Savannah, but in any halfway reasonable definition of pro vs amateur, she would be a pro IMO. Plenty of players in other sports have turned pro young, age and actual income aren’t really the right measure IMO. But in pool there really isn’t a standard, so I guess she can play any tournament that will let her play under their rules.
