Watched a lot of movies where gambling is done in the prison but it's basically illegal yet it's seen as the best way to entertain themselves but if caught in the act the person will be penalised, however gambling is something that seems to have to boundaries in our lives this days even the slightest things lead to gamble. I've seen kids gamble without a good knowledge of what they are doing and yeah I agree with you that gambling will always exist everywhere. One of the movies that seemed so real back then is a movie that fighting is a game and it's used for gambling, whoever is the strongest sometimes gets help from the outside to fight and get out of they win.
