You're correct. Gambling is inherently uncertain, and there are no guarantees of winning, regardless of how much money or effort one puts into it. Gamblers need to recognize and accept this reality to avoid disappointment and potential harm. Excessive or compulsive gambling behaviour often stems from a misguided belief that one can control or influence the outcome of games of chance. However, in reality, the outcomes of gambling activities are determined by random chance or probability, and no amount of skill, strategy, or investment can ensure a win.
Placing excessive hopes or expectations on gambling can lead to disappointment, financial loss, and emotional distress when the desired outcomes are not achieved. It's essential for gamblers to approach gambling with a realistic understanding of its inherent risks and limitations, and to gamble responsibly within their means. By acknowledging the uncertainty of gambling and reframing expectations, gamblers can make more informed decisions and avoid the pitfalls of excessive gambling behaviour.
I agree with your idea that excessive and impulsive gambling is always based on false beliefs, all this happens because of the hope they put on winning so that indirectly makes them "too sure" that they will be able to win when in fact the fact at the end of the session always slaps them that something they always hoped for did not happen and obviously excessive actions will only make you feel more disappointed. Putting hope and faith in a place that has no certainty is an action that will only make someone end up with addiction, logically when you are too hopeful but the fact is that what you expect does not happen then obviously you will not be able to accept the fact of defeat and this makes a gambler act more aggressively like chasing victory to restore something that has been lost, and this is a situation where someone starts to enter the addiction cycle. The point is that getting your hopes up on gambling can ruin your life in many aspects in the long run, and the mistake I think is that they don't look at gambling from many angles during the introductory stage like when they are beginners, which is usually people like that only look at one side of the "opportunity to multiply" which indirectly overrides the thought of the possibility of intolerable losses.
