In sports betting, luck also plays a very important role. A professional bettor can minimize the role of luck in the results of his activities due to a systematic approach and discipline, but the average bettor who makes several bets a month still depends very much on luck. Therefore, statistics show that most bettors still lose in the long term. In fact, every bettor who is at least somewhat interested in sports has experience, but this does not mean that his experience will help him achieve success. If you consider sports betting as a way to make money, then this is quite a difficult job.
Still, experience allows players to develop thanks to what happened to them in the game, but of course there are few such players, basically many repeat the same mistakes every time. In general, I think that watching streams of how others play allows us to pump up our emotional intelligence. Of course, many streamers can play even for non-real money, but if we imagine ourselves and how we would behave in many such situations with big wins and losses, then we would probably be more emotionally prepared for such situations. Although I am not a fan of streams with gambling, but for me this is probably the only reason why I can watch them.
