Betting with control is always the best, both in terms of money and strategies, it is a fact when we play that what is most needed is luck, I leave the strategies as for poker which is undoubtedly the best way to test your luck + strategy and can give you good results, but in the rest of the games I consider that luck is what you should have the most, sports betting is the exception, they are the only ones that are not made with luck but decisions are made thanks to our wisdom.
In betting, luck can sometimes also be decisive, but you are right that it will not be as important as in other games. But apart from luck and skill, you need to have discipline to stop when a losing streak happens. Because if you are going through a series of losses, it means that luck is not on your side right now, and it is better to stop and take a break. So everything matters, and luck in betting does too.
