For me if the person is already addicted to it then there is a low chance that he/she would stop even if he/she moves to a new place.
We have so many online gambling sites nowadays so it would really be hard to stop for someone who is already addicted to it.
If no one tries to remind him to stop gambling, he is less likely to stop, even if he has moved.
He will be able to find another gambling place close to where he lives or if he is used to gambling online, he will return to visit the casino site he usually uses to gamble.
But if he has someone who cares and loves him and doesn't want anything bad to happen to him, that person will always be reminded to stop gambling.
That is why we need help from others always to help remind each other.
