The problem most people have is they think that they can apply the same method they use in betting, gambling works differently because of the house edge, just like what you said people should always their mind to lose when gambling on casino games. It's a waste of time to come up with winning strategies when playing games like black jack or slot games. Some gamblers even try to use mathematical tactics but these things don't really work as planned.
I'm not too sure about how gambling game works but casino games are out of this world and I really wonder how people that won the jack pot actually does it. I don't really understand how they do it to make huge amount of money but they are always rare that when you see a jack pot winner in any casino, check again and you wouldn't be surprised that the person is definitely an Asia person because they are the only people that looks like they own these games.
I don't know for other people but gambling casino games are hell of stressfull, you have to be glued to your screen or maybe I'm feeling that way because I'm not used to all the games but I don't like something that will take all of my time. This is what betting gives you, do all you have and put the money and walk away until the events is completed before you check back and you don't have to depend on the casino but your luck will do the trick for you.
