Indeed right, when you still seeing balance inside your bankroll you mostly thinks that you'll capable to make things profitable unknowingly doing something that already hurting your balance to the point that you already lose everything, you keep doing that same mistake as greed mostly dominated us, hoping and aiming for big profits instead of being contented with some amount of money that you already earn,.
Always best to know and understand how to things works and how will you adjust for the betterment of the outcome of your game, it's your decision making that keeps you repeating same mistake over and over.
That's right, because when we have a balance in our money, obviously thoughts of gambling will arise because of great curiosity. We will think that when we gamble using this balance we will get more than our capital, but I am sure that when they do this they will suffer losses because gambling is just a game from the bookie or admin of that game. In fact, what gamblers do when they make mistakes over and over again is because they are addicted and their curiosity is so great to win that they do it over and over again.
So it will be very difficult to stop gambling even if they experience mistakes because they already have an addiction to playing. Unless they are aware that what they are doing is wrong and they only get losses rather than wins then it is very likely that the gambler will stop gambling.
