I think your input is quite good because instead of being used for gambling, it may be saved for savings or even invested.
but sometimes especially for addicts when eliminating gambling in their life it's like something is missing
make out income on constant basis then they would be thinking off that they could earn and spending those parts or funds in gambling wont hurt them bad
and this is a common behavior of an addict which you cant really stop them on doing so since they do know that they have money inside of their pockets
and they would bet as much as they could.
on the other hand actually when you say about profits it's just wishful thinking because no matter how hard you work, no matter how strong your capital is there, of course, the results are already guessed, won't it
Not without reason because brands (gambling houses) are great businessmen and we will definitely lose to them.
So, don't gamble too much
