It’s not just about borrowing from older ideas, it’s about the extent to which star wars was knowingly channeling a certain kind of story structure that has old cultural roots.
The Lion King would be a similar-ish example. It’s basically Hamlet, which Shakespeare based on an older Viking story (AFAIU) … so it’s just one of those stories that’s out there.
None of which is to criticise Star Wars, just to argue that it stands separate somewhat.
