Correct

wether they are calling a
turbo a "blower" or not, or calling the supercharger a "blower". It
can be sort of confusing, or to me it is.

The primary difference between a turbo and a supercharger is the way
the blower is driven. A turbo by exhaust gases, and a supercharger by
gears, belts, or chains.
IIRC, the Detroit blower isn't driven by the exhaust, so I guess
technically, it wouldn't be a turbocharger. Supercharger maybe, but
for some reason Detroit just uses the term "blower" all through its
literature.
