A cup is 8oz, or something like 240ml, which is about half of a typical drinking glass. That’s a lot of water. Here in the states, people challenge themselves to drink 8 glasses (so ~16 cups), and the recommended amount is 12-16/day.
Yeah, 450-550ml (16-20oz) is a pretty common size for a drinking glass at home or at a restaurant. We also have “juice glasses” which are about 110-170 (4-6oz) you mentioned, but not everyone has then. My kids’ cups are about 200ml (6-8oz).

A drinking glass in the States is 500 mL ?! That’s huge ! In my part of the globe glasses are usually more between 120 and 250 mL.

Its a hold over from cantines and waterskins. Remember a solid percentage of the US was effectively frontier 120 years ago.
