A friend of mine who is recovering from gambling addiction told me that the moment he gets paid he doesn't keep the money in his account for up to an hour so he doesn't end up getting tempted to use for gambling, he immediately uses those funds to pay up all his bills then send the rest to his savings account so he doesn't have access to it. He has made a lot of progress over the couple of months. Most gamblers think that going for therapy is enough, it's not going to do anything for you if you don't make a conscious effort to improve your life and make better decisions.
I feel almost the same or maybe the same as your friend. When I am in a state of enthusiasm to gamble, I sometimes can't stop myself from gambling, especially when I have some funds in my account, my hands itch to use them to gamble, do all gamblers experience this or not, I don't know but I feel it myself.
Actually we have other things to fulfill such as paying bills, yes that's right and others, if we do have bills to pay then we must be able to prioritize them when we have money, but with those who are addicted it will not be easy to restrain themselves when they have money even though they have bills to pay but the strong desire to gamble will make them prioritize gambling rather than having to pay their bills.
