You have to find out for yourself in your own context what you feel comfortable with. Consider casino, slot games or any gambling game. In each case, there will be more losses than wins. Determine which game is more accessible to you. Gather information about the teams, bet with verification and devote yourself to gaining experience. Beginners should spend time limiting their winnings in gambling. Beginner gamblers should avoid taking excessive risks and gamble. Continuing to gamble with pleasure can give you some relief from addiction but I doubt that this is right for all gamblers.
Not in every game will there be more losses than wins. If you are a good bettor, and especially if your strategy involves betting on relatively small odds, you will have significantly more wins than losses. So it all depends on the specifics of your betting style. What can really help a beginner limit their losses in gambling is setting a budget. If you set a budget and strictly stick to those limits, it will also restrict your playing time, because once the money runs out, you simply will not be able to keep playing.
But before you start playing, you need to clearly understand how disciplined you are when it comes to sticking to those limits. If every time you play a little longer, bet a little more money, or place a few more bets, it will gradually pull you in and eventually lead to bigger losses.
