There are different kinds of person in the world, there are those that will prefer to play nust for fun, and those that are really in to gambling because they aim for profits but if I were to evaluate these two, I think those that play because of profits are quite more frustrated unlike people who play just for fun. For me, I always play not because I want some profit, I play because I try to consume free slots and game offered by various gambling sites, just for the intention of fun.
Agree that we gamble for fun and make money but as you say, an overwhelming proportion shows that people who are gambling to gain profit are taking up the majority while the proportion of people who want to maintain happiness is decreasing, that can give us a link to a situation where fun is just the inception phase, the result will be gambling to make money. You also will not be able to leave this spin when you continue gambling, money is the element that can manipulate and control people, fun is just the original concept when we haven't lost too much and inhibited in the game
