Of course, a gambler wants to recoup his previous losses in every game. But he faces losses again and again. Because gambling companies can manipulate people. They put a social proof zone on every gambling platform. Where people look very happy every day. When they are out, it seems as if they have all won some game or the other. In this way, ordinary people go to gamble with about 20% more interest. Which is a big mistake on their part.
So we should not give in to greed in any way.
Yes, greed is the number one factor that leads gamblers to keep pushing, but if you manage to control that you'll be able to avoid losing a lot, with your statement, those kinds of advertisement can really attracts more gamblers to keep trying and hoping that they'll be able to make some decent amount while trying to recover whatever the amount that they already lose, but suddenly they'll keep on losing their money most of the time they attempt to push forward to play.
