Depends on the area. German speaking areas and Eastern Europe do use lots of potato. Even the collagial name for German is potato

I'm Austrian myself. There's plenty of potato dumplings etc., but they're just variants of other flour/cheese based dumplings. Potatoes are important but certainly not indispensable.

Compare that to pork for instance. Remove that and you've removed like 50% of Austrian cuisine.
