It is true that you said that defeat is something that will never disappear in gambling, this will happen, it can even be said that 90% is certain to happen compared to victory, therefore no one will be able to make gambling a source of income in their life because victory is something that is unlikely to be obtained consistently. Those who have this perception, I am sure, will only experience chaos in their lives, one of which is that they will spend more money and time on gambling alone.
This mindset must be changed because it determines our future too, but I think for those who already have this mindset, it will be difficult to change it, they will likely continue like this by prioritizing gambling in their lives, they are very lucky who can realize it in a short time frame.
Yes that's the problem or the point because indeed defeat is something that will always be part of the game which is why the idea of making gambling a place to support all living expenses or even to get rich will never seem reasonable, as we often hear that "the bookie always wins" and that is also another reason that makes the idea prohibited in gambling. As you might expect, those who have this idea seem to be those who are in chaos in their lives and yes it is most likely like that, as we know that when someone is under pressure from financial problems, they usually often justify any means just to get money, even though the method seems unreasonable.
On the other hand, what you said is true that when a gambler has misunderstood what and how gambling really is, it will be difficult to change it and this is also one of the reasons why recovering from addiction is very difficult, most likely in the end they will only be made aware of various significant setbacks.
Actually, the chances of winning for this big host and for players who only have a small chance of winning in my opinion are quite clear, even those who are addicted are aware of this, but because of this victory, their thinking has become blinded so that they ignore the risks that are clearly certain to occur. I myself do not think about making gambling a source of permanent income even though I have skills, for example, because I myself think it is too risky to make gambling a source of income in life.
There is a possibility that they will be able to realize to stop their addiction if they get their awareness, because even though they are aware, sometimes this awareness is still buried by a mindset that only thinks about winning. There is a small chance that people who are addicted will easily realize and stop their habits.
