They absolutely count it the same way. Comcast just gives me a number for bytes used, with a limit of (IIRC) 1.2TB above which they start metering. Our family of four comes dances around hitting that basically every month. The biggest consumer actually isn't video, is my teenage gamer's propensity for huge game downloads (also giant mod packs that then break his setup and force reinstall of the original content).

I think a few hundred GB for a typical cord-cut household is about right.
