Making money from gambling is a complex activity, but unlike roulette, where almost everything is decided by luck, in sports betting you can independently decide on which outcome you want to bet on and the probability of winning is higher (especially if you bet on an event no more than with two outcomes). But to make money in gambling you need to have discipline, nerves of steel, the ability to manage finances and analyze events. For the vast majority of players, this is too difficult a task.
It's hard for an online casino to become a money-making machine unless you command luck to be with you every time you gamble so that you always win, but there is nothing like this in gambling.
Then there's one more thing I can't say yet: I've been addicted to gambling. Let's say it's the investment I want to make because of my gambling. In reality, it is still very difficult to get lucky in gambling, and most of the time we always lose in gambling.
The truth is that no matter where you gamble, in online or physical casinos, the name of gambling activities can never be used as a money-making machine, I understand that gambling has a chance of winning that can give you a large amount of winnings possible but what we must understand is that there is absolutely no guarantee or certainty at the beginning to be able to tell you that you will be able to win at the end of the session, It's all about luck and it means as you say that we will always be able to make a win if we can command luck to always come but the fact is that luck can never be known when it comes and this is why I often mention that actually the victory that you managed to get is nothing more than a victory that came by "chance".
This means that something that is only based on luck to produce will never be able to give you consistent results because after all your wins only happen by chance. I would say that no matter who you are and how you gamble, you will not be able to make the winnings come your way in the end, and this is why a gambler should never put too much hope in winning because in the end you will just lose a lot of money slowly.
