it's just hard to see someone who will be willing to consistently risk so much for so little.
I think there are actually a lot of gamblers who do this, especially when they’re trying to find a "surefire" strategy during a losing streak. Psychologically speaking, if they see that they have a 99% chance of winning, gamblers will expect to at least partially win back the money they lost earlier. But obviously, this is a false hope that not only fails to make up for previous losses but, on the contrary, actually accelerates the draining of their bankroll.
For a time maybe but never consistently, the risks are just too big for anyone to keep going for it over and over again, when that becomes the case then I'd probably think they just get a kick out of the risk of losing so much for so little, at that point it's no longer about winning but about the rush from potentially winning more than losing, from potentially winning enough to actually turn a good profit without losing, they are just pushing their luck at that point
