I don't think age has any effect on gambling addiction. Personally, I have an opinion that, people who have more free time are prone to gambling addiction. They just start playing for fun and eventually finds difficult to get rid of it.
Maybe experience can help us to stay away from addicition with the young people the experience of life may not be found at most time but if some one having much free time to spend they will be addicted to something for example if we are spending time with social media then it be our daily routine to check the social media every morning so which is an addiction so it same applies to gambling too.
If the experienced long time on gambling definitely they will be advise us to stay from gambling investment but they will involve themselves alone on gambling for sure.
Addiction stories are many on gambling as like that we will be able to find the loose fund completely from your pocket.
Looking at the level of addiction these days, you will tend to find out that most people that get addicted pretty fast are those who have the mindset that gambling can set them on a good course to get rich overnight and that is one mentality that can be applicable to anyone but I certainly understand this is something that can be more common among the young ones.
A reasonable adult who has experienced certain things in life, has heard different stories, and is wise enough to make decisions, will always find a way to control themselves.
Nevertheless, like I said, this does not mean we do not get to see adults that gets addicted too as well most times, so in a way, we could just say as long as you have the wrong mindset either young or old, you are still prone to gambling anyway.
