I'm just saying that cartels being in control of drug aren't hurting Chicago's mob. As far as the other things you mention your right they have hurt all loansharks. But many folks rent house and don't have credit. Online gambling doesn't offer credit. Plus now-a-days betting with a bookie is the for lack of a better word "sexy" thing to do. Even more so if they are an "associate" which everyone is labeled in this day and age.
