I do about 600 to 700 GB each month, but please do not think it is not feasible for most regular folks to max out their data for the month.
My 600 GB plus is for my desktop PC, all of the IOT devices, casting devices, smart TV, NAS boxes, music streaming, gaming, etc.
However, a good chunk of video streaming from the likes of YouTube, Hotstar, and Prime Video is actually consumed on mobiles and tablets that run exclusively on Jio, so the data from my ACT Fiber is not counted. I'm sure if all video streaming were on ACT Fiber, it will certainly cross 1 TB. However, the wife prefers the smartphone and the iPad for quite a bit of the streaming. She regularly watches entire seasons on her 6-inch smartphone or iPad using Jio as opposed to the TV or PJ (that are not on Jio).
