Gamblers worst loss can happen at anytime, especially when we can't afford to take the incident of losing a bet for any reason after being confidence in it to be a winning game, which is more better for us not to work by assumption, instead focus on gambling according to how we can risk it for lose, for now, all i can say is that we are used to it already, no more gear comes in mind whenever we lose, because it's part of the fun.
When someone becomes overconfident in gambling, they tend to take excessive risks. At some point, when they take risks despite not having the ability to take risks, it starts to have a negative impact. In the case of gambling, I think this is the worst part. When I bet more than I can afford to lose that money, that will be the biggest loss for me. My worst day in gambling was the day I became aggressive to recover my losses.
