The fact that we always complain why we are consistently at loss, that only proves that casinos are designed to make us lose while leaving them gaining the best advantage. And casino is a business, so they will always make sure to keep those profits and grow their business, even if it means a big loss for us.
This is why we should be gambling responsibly. And gamble only on our spare money, because we are designed to lose and make the house constantly in profits.,
Yes, basically it's a good idea to treat gambling as simply a recreation, and budget for it if you want to.
There's no real money to be made by gambling, and the only people making money is the casino owners.
It's true that it can be fun though, but that's why you need a budget.
