Let me get this straight. If they have 0 tolerance, then the worst ones will be ignored?

Oftentimes, yes. If a zero-tolerance policy is in effect and resources only allow 10% of "intoxicated" motorists to be caught, then a lot of dangerously intoxicated motorists will not be caught because of the resources allocated to the harmless ones.

No, the object is to go after the worst ones and ignore the people who had one glass of wine with dinner (who - surprisingly - can pay fines).

If drunk enforcement were limited to cops driving around at night, paying attention to the traffic, and watching for drunks, they'd catch the genuinely impaired ones. When they are stopping random, normal-driving motorists on pretexts, or raising speed limit money, and sniffing for a hint of alcohol that had no visible effect on driving performance, they are busy at the roadside while the swerving drunk drives by.
