Casinos can't allow you as gambler win when doing so is detrimental and dangerous to their finance, and this is the reason why the make there provably fair, which means player or gambler have 50 percent chances of winning, and 50 percent chances of losing their money to the casino, but the casino not willing to accept any form on loss, have to introduce house edge, to further increase the gambler's chances of losing his or her money to them(the casino).
It is important we all understand that it's humans like us that run online gambling casino, and this people need money just same as we the gamblers all do.
So, gambling is a game of, gambler verses the casino, whoever wins takes home the money, and as we all can see, casinos have been pretty good at winning, and the reason for this should be very obvious to those experienced gamblers.
In a game of man versus casino, the casino always wins. Because man is an emotional creature, he is prone to hasty and ill-considered actions, and a tendency to gambling. The casino simply figures out how exactly it needs to earn money, it is impersonal, and it has no personal intention to win from the player. Players tend to make mistakes that lead to losses. Moreover, they tend to want to win back, to recoup their losses, and this feeling often leads them to even greater losses.
True, humans are social creatures who have feelings while casinos are systems that have been set up, so as you said that humans are more likely to make mistakes that are driven by various factors such as curiosity, loss of awareness and inability to accept circumstances that can trigger emotions and various crazier actions that will indirectly make the casino even more profitable.
And I am sure that the casino dealer already knows that there will be a lot of carelessness that will be done by gamblers based on curiosity and greed which ultimately unknowingly makes them fall and fall.
Therefore, this is why from the beginning we must consider carefully before finally deciding to get involved in gambling activities, try that the decisions you make are based on rational thinking in making considerations, and this is also the reason why caution and awareness must always be maintained while we are involved in these activities.
