Yes. Yes they are weird buffers in that you have to spend some (minor) effort remembering what exactly is in the "clipboard", "selection", and the difference of invoking them between apps (e.g. having to Ctrl+Shift+V in the terminal).

Oh, and the fact that selection buffer gets overwritten if you switch between apps with active selections.

Oh, usually there's also a cherry on top in that everyone's darling, vim, doesn't even interact with any of those and has its own buffers aka registers.

I'm sure if there was a way to track how many time you make and undo mistakes in copy-pasting the wrong thing from the wrong buffer, your assumptions would be seriously challenged.
