I think that there should be no such thing as blaming someone for our losses , because we must be responsible for our actions, If we play in a casino and lose for whatever reason, it is our own fault, and no one else's.
Actually, there is no logic in blaming someone else for your loss, did someone give you too much hope for gambling? Did they force you to gamble? It's your money, so if you wanted to stay away from gambling, could they have done anything? No, in fact, we have no logical reason to blame others, you gambled with your money with full knowledge, so if you lose, you will be the only one responsible, there is nothing to blame others for.
