Gambling can't ever be a source of income or a cash cow even if a gambler thinks that he has found a pattern that he can use to win, unfortunately, so many newbies fall into this trap and it takes them a large amount of losses before they realize that luck and not pattern are the keys to win gambling.
Doubling or multiplying your money is very attractive for gamblers but they fail to realize that the gambling platform is a profit-oriented company, for every ten bettors only 1 or two will come out a winner, and sometimes none or there are no winners.
Gamblers do not consistently win in gambling, but they often lose most of their betting capital. And even if they have found patterns to win, there is no guarantee that it will always be granted since the edge to win is always on the casino house, not on the gamblers. This is why there’s no assurance to be in consistent profits with gambling. You can be lucky and make a big win, but most of the time you end up losing all your funds and go home with empty pocket.
I think it is certain and it is a fact that most gamblers experience more losses than wins, and if we don't believe it then we can actually record the number of wins and losses in our budget from now until the next few months and see the results where I believe that it is very likely that the number of losses is definitely greater than the wins and I think this is natural because maybe you have also often heard about the idea that winning is actually only for the casino itself. On the other hand, yes, I also have a friend who really believes and believes in a betting pattern such as in random betting types such as slots, he believes that this pattern can produce a win, even though in fact the possibility is very small, or even has no effect.
However, we have to return to the actual fact that there is no way or pattern or strategy that can guarantee victory at the end of the session, and yes, it is true as you said, this is the reason why gambling is often referred to as an activity that does not have any certainty or guarantee because However, only luck can bring you victory, and this is why it is always recommended to limit your expectations of winning.
