Gambling is completely based on luck and no strategy works here, it is true, but this is only for casino games. When it comes to sports betting, predictions definitely work, and you can win by using different strategies. Because live games are played here and predictions can be made by analyzing the players and clubs. A good horse will always run faster, but due to some physical illness, that horse may run slower one day. Something similar happens in sports, a good player may play badly one day due to his physical illness and that team may lose that day. Most of the predictions in sports betting work well, only sometimes you have to lose here. So sports cannot be completely compared with casino.
Sport betting and casino games are two different types of betting and when approaching them you can't use the same strategy or you're going to lose. You'll have to analyze the clubs that are playing to find the weakest clubs to bet against unless it's a rivalry clubs playing that the clubs with the biggest strength don't use to always matter or it's a club that has good history of always winning the other bigger club then you can bet based on that information that you have.
Sport betting is like trading that you'll have to analyze the market before entering but when playing casino games, you can rely on your instincts and hope on luck to make you win hence although they're all called gambling, but we need to know the difference so we don't think they're the same thing.
