Gambling with high expectations is not advisable the game is supposed to be for entertainment and not to get your hopes high on getting money to solve your problems. Anytime I gamble with the mindset of planning to use my wins for something it always ends up going sideways. You can never control the outcome all you have to do is gamble responsibly and don't think about an amount of money that is not in your possession
Almost any gambler playing gambling wants to win money, as only this brings positive emotions. In my opinion it is impossible to get dopamine or adrenaline if for your gambling session will not be at least one win. If everything was different everyone would play gambling in demo mode and do not spend money. Try to offer to play in demo mode to someone who says he gets pleasure from gambling. I'm sure he will refuse.
