I gamble because I want to and it doesn't matter whether I have sufficient or insufficient money, that's what matters to me. But with that, it's better to gamble because I have sufficient money for me to gamble without any problem and I won't be pressured to win them back.
That's the typical reasoning why I should gamble and others are gambling to cut the fun but to take the possibility of making huge profits.
Yes, it is important to have enough money for gambling. Let others say what they want, as long as you are having fun and only using your own money to gamble. It is crucial to be responsible for your actions and only gamble with the money you can afford to lose.
One should not overstep one's limits for gambling as betting beyond one's means will create greed among people which will put everything under pressure. Even if you gamble for fun it is better to keep the gambling money separate so that you don't have to suffer more losses even if there is a possibility of losing.
