Winning the casino sounds like something actually impossible but let's take a second look at it from a perspective of relativity, technically it never feels like you have won the casino because the casino is in for the long game which you may not be aware of, there are times you will get to win a lump sum of money and the feeling will be like the casino just lost, but actually if you will still continue gambling, then the casino hasn't lost just yet.
I know of a friend who won a good sum of money and he said so far all the money he has lost to gambling, if summed up, it will be below that which he just won but the interesting part is that he didn't stop gambling afterwards although I have not kept tabs on his gambling habits recently but I think if he is still gambling, by now he would have lost at least half of that money so far, or may have lost even more, so you see why the casino looks like they can never loose, it may take time but if the gambler keeps coming, the casino will get back what looked like they once lost.
