The point here is that the POSSIBILITY of making profit from gambling makes the game entertaining. You don't have to always win, but just to have a chance of leaving with more money on your pockets than you came in, it's already a rewarding mindset for many gamblers who practice this hobby for years and even decades, without harming their finances, social relationships and their emotional.

The problem is that there is a new generation who was introduced to gambling just now and think they are entitled to always win, otherwise gambling is bad, should be banned and everyone involved on this industry is guilty for my losses...

The only truth here is that gambling isn't designed to be a job or extra income method.
