Gambling is a game of luck, and you cannot expect to win at any time, have luck, and win while complaining about it. In my opinion, if he can't take the risk any longer, he should leave gambling because it doesn't favour him, which is why he is winning small amounts of money. He should instead look for another business or something else that will profit him before he starts betting too much and becomes addicted to it. Gambling is a game of chance, and if you lose today, tomorrow he may favour you, and you will always expect to win when you bet because it is a risky game. Bet with money you can afford to lose, not the one you will be regret why you bet on the game. That is why I bet for excitement whenever my favourite club has a match, so I can enjoy watching it. So, if he is unable to quit betting, he should reduce his playing time so that his money lasts and the bet does not profit from him.
