Variac is usually an auto-transformer. Actually, Arran answered it. It's like Russians call all SUVs "Jeeps". Or we used to call all refrigerators "Frigidaires".
Then there are isolated output Variacs. Those are also autotransformers with the output going through a transformer. Or could be vice versa (can't be sure - in theory that is possible).

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
