The link i provided is all the HP drivers you'll need for MacOS Big Sur.
You asked “Why are people saying that HP printer officejet 4500 g510n-z is not supported by Big Sur?”, and I presented a reason why that presumption might exist.
HP may well have retired that printer, and not yet removed support from the omnibus driver kit. Or nobody at HP has updated the printer support page since OS X 10.9. Both have seemingly happened over there before, too.
And vendors do tend to have a specific definition of “support”, which can differ from whether the widget works or not. Based on the printer support page, that printer does look to be unsupported with releases after OS X 10.9.
