Saying that playing games always results in success over losses is simply flatly untrue Its comparable to declaring you will always be a stock market winner. Yes, you may have some good days, but over time the chances are stacked against you.
Well there is something that may be very true, when we play in a casino often, we know that in the long term we will have losses, that is very normal, but that does not mean that we stop winning, getting a more positive balance than negative is very difficult in gambling, in fact one of the things that I have discovered is that winning little, even a profit of 1 dollar, then one must see it as a business, be content with that 1 dollar for the day, and if the next day or the next game session the same profit is made, then one must do the same, and over time is when the profits are seen , but in the very long term.
