Although a person gambles for entertainment, when he loses in gambling, he cannot console his mind easily because financial loss is a very serious matter. And people can accept loss according to their weight like if a billionaire loses a million dollars he can easily accept it but if a person has total assets of $500 then even if he loses $100 he can't comfort his mind and he will suffer a lot. And that's why everyone should gamble according to their abilities and follow the limits for gambling to be used as complete entertainment.
This is the reason why gamblers should only risk what they can afford to lose.
Every gambler, if they really want to get consistent wins, they also have to take risks with money that they are ready to lose money. If it is calculated to get a profit of $ 100 with a little capital, it is clearly impossible, especially luck is needed in gambling, not every day gamblers have luck, so it is difficult to get $ 100 consistently except with a capital of $ 100k and even then of course not consistently because there will always be a risk in it.
Op will never be able to consistently make $100 profit because it's really hard to earn it every day so like I said before that to get that achievement they have to be prepared with the money he can afford to lose.
