If I check on monkeytype it's around 130wpm but as others have said it really depends on what you are typing.
(for what it's worth I learned to touch type on an old typewriter decades ago, however my wpm was much slower then as the typewriter would lock up if I typed too fast)
Right if I'm doing a typing test, I can do 150 on a good day with good posture and being warmed up. Typing tests are really picky about accuracy --if you have a single typo, it'll kill your WPM and they typically won't let you continue without correcting it to be exact, plus you're usually reading & retyping exactly what you see including every bit of punctuation and exact capitalization.
But if I'm typing casually, e.g. a discord chat or certain types of code, it's much faster. I imagine the other fast typers here can reach insane speeds in these contexts. The way I can describe it is you have clusters of letters where your fingers hit the keys at almost the same time, and it no longer sounds like distinct key hits.
Edit: the keyboard selection matters a lot too. I'm nowhere near as fast on an IBM Model M as I am on a modern laptop (chiclet?) keyboard. I'm a little slower on a thinkpad than I am on a Dell or Mac laptop. A real typewriter would be the slowest as the metal can get all jammed up --that's a unique skill in and of itself.
