I'm not really sure that gambling is for people to make money unless we are talking about professional poker players and their likes, or any other games which apart from luck also involve a certain amount of skill. Chance games are about entertainment only, and if you somehow come to think differently, it may cost you dear. Regarding casino owners caring only about their pockets, isn't that as true with respect to casino players who equally don't care about the pockets of casino owners?
If you are after money, gambling is the last thing you should be looking into
The best is to understand that it is possible to play games without using strategies and yet make money, I feel strategies is really the problem with gambling and again, it is highly important to overcome greed since this is one thing that prevents gamblers from being successful but making money is definitely not restricted to professional gamblers alone.
