The bottom line is that gambling establishments, like land based casinos and internet casinos, are set up to take in more money than they pay out. This means over time, you will lose more money than you win. But, remember it is not just casinos, all forms of gambling have the same principle – the vast majority loses so that a very small minority can have big wins. Virtually all people with gambling problems hold the false expectation that they are the ones who will be the big winners. That belief feeds the problem.
