And you probably have a lot of files still from removed apps. There’s a reason there’s a few app uninstaller / cleaner utils

Yeah but I don't actually care if some orphaned cache or config file gets left behind if it doesn't take up GBs of space.

Clearing the package receipt database of stuff you want to uninstall is fucking neurotic, I'm sorry, but it just is.

There is a new way to make apps to mostly allow this to work, but very few apps have taken advantage of this. That is definitely on Samsung. However, macOS was really like this for many years and if you ship software that talks to your SSD you kind of have to make it this way.
