“Liquor” has two senses - a narrow sense in which it refers specifically to beverages produced by distillation, and a broader sense in which it refers to alcoholic beverages in general, including wine and beer. The narrow sense is stronger in the US (and I think also Canada?), whereas the broader sense is stronger in the UK and Australia (and I would assume Ireland and New Zealand too)

I always thought "liquor" was stuff like Lemoncello and Amaretto.

(FWIW I'm a native US English speaker.)

You may be thinking of liqueur.

Yep, liqueur is cutesy syrupy stuff made in european monasteries or whatever, typically around 40 proof. Liquor (as in "corn likker") is the stuff for getting messed up fast, typically at least 80 proof.
