Playing and engaging in gambling activity is indeed a personal choice but no players ever wanted to be addicted on gambling. Gambling addiction just sprout from the activity of a person. It develops without the knowledge of a player that is the reason why I think gambling addiction is not a personal choice.
Many factors gamblers are very inappropriate for underage players so that they do not have the emotional control and attitude of maturity for important decisions, so gambling addiction in underage players should be avoided because it will damage their education and mindset when they are teenagers. I will always advise gamblers under the age of 18 to leave gambling because they have not yet reached the age set out in the requirements.
A minor's development will be stunted if he spends time in gambling when education is needed. Neither morality nor common sense resides in it. And neither the family nor the society can expect anything good through him. Rather, we have to face various problems. He will never be able to control himself in the gambling world. Consequence of this, he will lose everything. So according to time and age it is best not to engage in such activities until becomes mature.
