Here in the UK we don’t have data caps but our personal household usage roughly is 500GB a month between 3 of us on 65Mb. We don’t do anything other than stream in 1080p and I’m the only one who games. I don’t know about upload usage, of 20Mb, never actually asked our ISP.
The UK is on average about 456GB in May 2022. With the UK passing over 60% of households having fibre to the home as of late, that number is likely closer to double that now; especially as more people can watch content reliably in 4K and upload more since WfH etc…
