There is no way one can gamble for fun and don't have small intentions of gambling for money.
But like I said, it has been made clear to the person that gambling is dangerous if you are using it to chase money, that the end result or outcome may be bad. It is easy for newbie gamblers to understand that. So if they gamble and chasing money and lost money often, they will know they have read about not chasing money while gambling is true. Gambling with small amount of money will give you a peace of mind.
If we refer to the dangers of gambling then obviously the best decision to make is "don't gamble at all", this is the best choice if you absolutely do not want to lose money for nothing, and if you still want to engage in gambling then obviously the choice is that you must be able to accept the fact of losing at the end of the session and never gamble with the idea and purpose of "wanting to make money" because it is a bad idea that you can never achieve unless you are a croupier or casino owner yourself.
After all, casinos are a business to benefit the house in the sense that anyone who tries to take advantage of the situations and opportunities that exist in gambling then usually the opposite happens is that you will actually lose a lot of money slowly and sometimes it's not realized. One of the reasons why gambling is better as a place to seek entertainment because there is absolutely no certainty that can guarantee you to always win at the end of the session, and as you said I hope that most novice gamblers can understand about the facts that exist in gambling so that they are not lost or wrong way that ultimately makes them suffer a lot of problems in their lives.
