Yes, people tend to blame others for their mistakes and failures. That's just the way their brains work. More precisely, they are not smart enough to understand their mistakes and accept them properly. This is a poorly developed intellect. There's nothing you can do about it. You just have to pass by if you encounter such characters in your life. I know a few of these people. I've come to the conclusion that it's better not to have any contact with them at all.
Blaming the house is irresponsible, players are better off owning up responsibilities, and accepting results. Players who blame the house always have lesser energy and end up with a crushed problem solving skill, which won't be nice at fighting the little issues or signals that walks most players into the compound of problem gambling.
There is no point in blaming the casino house for any loss, those who do such baseless activities are actually fools, the casino house is never responsible for any loss, so instead of behaving irresponsibly towards yourself, be aware while gambling and pay attention to your ability, do not gamble with such an amount of money that if you lose, you have to face a difficult situation, due to which you get emotional and start blaming the casino house for no reason, if you are responsible towards yourself and play according to your ability, you can accept any loss and keep yourself away from gambling, as a result, you will never suffer a big loss.
