It is not only addicted gamblers that don't consider gambling as an entertainment because some other folks don't also see gambling as an entertainment because they are gambling to make money or gain which is a common reason why so many people gamble. Addiction is very bad because it can totally change the way someone see things in gambling and that is why even when they are making loss they won't stop or take a break but instead they will be serious with the gamble.
You are right with what you say, I think many people expect to get some cash from gambling but they don't depend on it to make a living, that's the difference between addicted gamblers that want to make money by all means and a gambler that see opportunity to eat, drink, pay bills and even take care of themselves. Fair enough such people rarely see penny from gambling and they are the type that risk much when they want to bet because of their expectations.
As long as there is money in gambling, accept that people will have different opinions when it comes to gambling, they will do what they want and I don't have problem with it, just know that I will never borrow you my momeh because you want to gamble, I will not give you my money because you are addicted and sold all your properties. If you want to make money, go outside there and do some jobs. I'm sure if they remove money from gambling, they will stop going to casino.
