Those payoff stats are not accurate and that's not even close to how professional gamblers operate.
They play in tournaments for prize money for starters...
Did the shooter do that? There are claims he didn’t like to deal with people and liked to play in a quiet area. So could he do tournaments that way? I don’t know anything about how it works, I thought the tournaments were more public.
If he could do tournaments then possibly he was able to make that kind of money gambling.
