A person who is gambling to have some fun isn't a gambling addict but if a person doesn't have self control then that person can become a gambling addict easily. To prevent yourself getting out as a gambling addict is to make yourself busy like starting a new hobby as to make yourself don't have time for gambling and a rehab. I am sure that it will work quite nice since you no longer have time for gambling and also have someone teach you about financial management.
Sometimes it takes more than starting a new hobby yo stop addiction, the reason why I'm saying this is because there are people that I know that started learning how to play videogames just to quit gambling addiction but somehow they still find theirself back to gambling. It's all about having self control and being able to stand on your decisions of not going back to it, distracting your mind with a hobby might not be enough
