I've been coding professionally for >30 years. I don't think any of my code has survived 5 years in production.
I don't think code quality affected that at all - I know the really, really, shitty code I wrote when learning OOP in the 90's survived for a looong time, while the amazing code I wrote for a startup 2018-2021 died with it.
I haven't doing this forever (only 10+ years) but surprisingly I think a majority of what I've written is still running. Probably a fair bit will continue to run for a while yet too I think (again, surprising for CRUD web apps).
