I don't know if the USA is representative of the rest of the world in this regard but, with respect to drinking, American adults fall into deciles that surprised me[1]. Roughly 40% consumed almost no alcohol in the week before being surveyed, 40% were low-to-moderate drinkers, 10% averaged about two drinks per day, and 10% holy shit that's a lot of booze.

I think that chart is misleading, 0 drinks in the last week does not mean "doesn't drink at all, " which implies total abstention. You can easily go weeks or even months without a drink as an occasional drinker who only partakes at social gatherings.

Going a week without acohol is considered a category below low-moderate acohol usage? That seems weird to me.

I would describe myself as a low-moderate consumer of cake. I definitely don't eat it weekly.

Keep in mind the parent comment essentially selected for these people ;)

I am one, for the simple reason most of my male ancestors were alcoholics and I decided the easiest way to not be one was to avoid it entirely.
