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.
Individuals who are constantly searching for someone or something to blame for their losses are not mature. Blaming won't even make up the money you lost; accepting responsibility for your actions is the best course of action. Additionally, I dislike those who criticize or even assign blame, even when their acts were the cause. And the reason they place the blame is that they always strive to appear flawless, as though they never make mistakes, and when professionals falter, it speaks more well of common people.
When the time comes when they will be unable to place the blame anywhere, they will turn their attention to finding ways to make up for their losses. They fail to see that there is no shame in losing. No one would hold me responsible for introducing them to gambling because I don't even introduce people to it, and even if I did, why would you hold me responsible when it was all a question of choice? Not a single cause to assign blame. Either they blame the casino or say anything it won't change anything.
