Define drinker. As is, it seems to be a poll not on the distribution of alcohol consumption, but on the social acceptability of alcohol—which is also an interesting question, just a different one.
When drinking a lot becomes less popular, I’d expect drinking a bit to become the common case, not total abstention, and those people might still self-report as “drinkers”, even if they e.g. refuse to drink at parties.
