Are you sure that you have never won even once? The statement of "the house always win" applies for those who desperate in their gambling journey. It can be due to bad money management and bad self control. To be frank, I do not believe if you have never won even once. There must be a time when you won some but you could not stop so you lost it all eventually.
You are right, there must be something wrong with the players if he never won or even saying about "the house always wins".
Although the house always has bigger chances to win, there is also a chance for us to win. Of course, it will depend on how we play or gamble, including what you said so. Good management of the funds, strategy, risks, and emotions are the combination that should be paid attention to.
Don't take it word for word I must say. The meaning of the "house always wins" here is that in the long term, users would only lose money, and not really win if they were to keep gambling, while the house, would always earn money even if you win, since you're just going to gamble it back. It's a simple but vicious cycle. Heck, even if you win, just consider the amount of money you actually lost before winning that amount. Sure, you may be one of those rare people who won after a few games, but that case is rare a f and can't really be considered as a normal situation when taking into account other gamblers.
