If you want to know how much money you need to have drowned before gambling becomes the issue then you should also ask how much money do you need to win before you know that gambling is also the problem.
but if you win, then gambling is not a problem
gambling only is considered a problem when it’s.. making problems when it’s making you suffer when it’s making your life worse than it is but if it’s made you rich then how is it a problem? too many money to spend?
