What am about to say applies more to those in the lower and middle class very often. Most times when you find those within this social status gambling more than they can afford to loss, it’s probably because they’ve got plans of what they could do with the win money and as such, they’ve taken a step to go for less risk but more stakes. This would be some means to bring themselves closer to winning but in reality, the game could always play either ways.
In the event of a loss, you could imagine just how broken such individuals would be. More frustrated than you came. A lot of people have found themselves in a suicidal position with that. Loosing is never easy to get used to or suck up and as such, you need some know how at the game to leverage for your advantage.
