Some people are the cause of their problem, it's not as if they are not aware of the risk of gambling, not that they don't know that they will encounter losses but they kinda have some confidence that they could be very lucky more than anyone else, they forget to realize that it doesn't work like that. From what I have seen so far, there's no addicted gambler that would say "they didn't know that gambling is a game of luck, " They know but ignorant caused them become addicted.
Too much confidence made them ignorant. That's how it ended for them, they're aware of the risk and the ugly outcomes that they might encounter and yet they still did what they don't have to do. Those that have became lucky gained more confidence and that's what they have carried on for their next gambling bets and it didn't do good for many. We knew how it will end up for us but we should still keep reminded and become responsible for as long as we can be. Always think of how to gamble safely without compromising our very own bankrolls.
Those who gamble with high confidence gamble with large amounts because they think they know the gambling algorithm very well and they are sure to win. Their confidence and attitude push them towards destruction. I don't know who can gamble with confidence, because gambling is a game that depends entirely on luck and no one can guarantee their win. Those who get excited after seeing a few gambling wins and start thinking of themselves as gambling experts will eventually lose everything, this is true and it always happens. Therefore, it is necessary to be responsible while gambling and one should definitely gamble with a limit if one wants to protect oneself from destruction.
