I think that when we were younger, we all thought that we would find some secret that would make it easy to get money from an online casino. It seemed that everyone did not see what we could see and understand, probably this is youthful maximalism, and it is he who does not allow us to stop looking for the secret of permanent earnings. Unfortunately, the casino is able to turn this wonderful desire into an addiction in which the gambler continues and continues to play, completely unaware that the casino has long been protected from all sides, and will not give players any secrets on earnings. Only for losing money.
Some people or the adults can of course see or think what young people are thinking. Some of them spoil the fun for the good of that young person, while some just let them because being young is not permanent anyway. It's not the casino that can turn us to be an addict but it was us if we don't stay to be realistic and aware of some things. Even for losing money, casinos won't share this info because it will obviously ruin their business.
So, they are actually giving a hint that you can make money (tons of it) when you play on them. This is also what we call as marketing. Some of us already know that it isn't real but we like to be dumb and fall for it.
