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.
