honestly it's hard to imagine that a person can lose 40 consecutive times, to be honest that person even playing dice at auto bet won't have so much bad luck to the point of losing a lot consecutively, but nothing is impossible in gambling, if the person loses more than 5 consecutive times in sports betting, then this person needs to stop playing with greater urgency, otherwise this person will be walking towards addiction and will sell everything he has to continue playing, because in games of chance in which luck depends on winning if the person is not lucky enough to win something considerable even when he has played many games then he needs to stop playing that game and try another game
Well, if the person losses in sports betting 5 consecutive times, it means he needs to stop because of the possibility of addiction but because he has no skill or knowledge about the sports and the teams behind it. He is probably just guessing making sports betting a game of chance instead of skill-based.
5 consecutive lose doesn't mean of addiction it just state that he doesn't know anything about the sport he's betting so maybe he need to do proper researching and watch the sports so that he can familiarized them. It also give him a lesson that betting randomly cannot get him anywhere so he need to be more smart placing his bets so that he can win next time and avoid losing for 6 times.
