Thanks Frank. But to many people Profit does not equal fun. And it is okay to spend money (aka lose money) to have fun. And in a casino fun can be the thrill of throwing dice, of the turn of a card, of watching the wheels spin on a machine.
As I wrote before, I had plenty of fun collecting coins, and as a kid I had plenty of fun collecting stamps too. They were not profitable. (In hindsight, had I held on to those circulated, common date Washington quarters with 90% silver I would have a profit today.) But it was recreation.
I can understand how you say that some people who figure that "losing less" is "winning" is a serious issue for psychologists, but I don't think that applies to most people in a casino.
Besides, many times people say things that they don't really believe and really don't mean. Many people come back from Vegas and proclaim that they were "even" but they know they lost. It's just something that people "say." People sometimes just "say things" without really meaning it.
