I think this only depends on the gambler. Some can have a hard time on restricting them selves towards gambling, so they think the solution is to cut it off completely.

As for me, I already attempted removing gambling in my life (completely) by uninstalling the gambling applications that are installed on my devices but then I find my self re-installing them after some time because I feel so empty. I know it must be because of the decision I made on the past and then when I play, I feel happy again and then something is telling me that I can do this better this time which is true though. So, now I know how to discipline my self in case I relapsed again.
