Not a universal experience though: also a US Millennial, in middle school/highschool our history classes were pretty much only US history, and only touched world history as GP described. We did have a world history elective in highschool though, but it was an advanced placement class and not everyone could take it. No history classes during college.

Additionally my history classes all ended around the 60s-70s - roughly when the teachers were kids. Seemingly from their perspective "history" didn't include anything they experienced.
