Mostly I do advise that the best way to gamble is to learn gambling and also take it as fun, this will help in so many ways because you're not going to be running after loss in playing games and you can't be deeply attached to doing what may later harm you or had to leave, this is why a responsible gambling is well admonished, so that things will often be in place for us as we are gambling from time to time.
Learning can be done in demo mode but many people don't like to even test the demo and that begs the question if people are gambling for money or they are gambling for fun. The same experience they are getting from real gambling can be gotten from demo, the only difference is that one will require money and one will require nothing but someone who has no experience will want to use money to try something they don't understand and expect to win.
If all gamblers learn about gambling and do everything possible before real experience, I'm sure that many gambler won't like to gamble again, they will rather just have fun from other places, only when they have the money to play that's when they start and that tells you that everyone are gambling for the momey and not the fun that is been described everyday. If you check, a lot of people are gambling for the financial reasons and not any fun that is been spoke about.
