People need to hold onto something. So I think, when losing in gambling, they need to blame something since they can't really pinpoint who to blame because it is themselves that do the betting. They can even go deeper by blaming some of the people who introduced gambling to them, or they can blame the team and think that those games are rigged and being controlled by some group or mafia so they can take profit from them. Or blame the casino or the gambling app, saying that casinos are manipulating the game. If the gambler keeps going like this, he or she might get addicted since he or she cannot control his or her emotions.

As gamblers, we should not blame everything when we lose. Since "gambling" is risky, we should know that in the first place. So whenever consequences come, you should face them and take them.
