It just seem like one needs to be properly guidedon the wings of gambling so therefore there's nothing wrong in letting them know the both sides of gambling and leave them with their own choice of decisions but they'll be glad they knew the negative snd positive sides. I believe it's based on the negative occurrence that has led people to withheld the good sides of gambling.
They will only realize the bad side of it when they're no longer winning and they're spending too much already.
There come a lot of realization at the end and it's true that it will be their choice that they need to do if it's gonna be worth it for them to do more or force themselves to control it.
