It will depend on their addiction level. A person, who has just started gambling but is finding themselves getting hooked up with it slowly, might not have a lot of problems and can easily slowly quit gambling if they want to. However, if a person has already become extremely addicted to gambling and doesn't have enough patience and self-control to say no to the urge to gamble, such people can't quit slowly because they can't stop gambling because of the addiction.

People from the second category I've mentioned will never be able to get out of their gambling addiction on their own but will always need assistance from someone else. However, the first group can easily quit gambling if they try because they are not too deep into it yet and they can still take a U-turn.
