Org files are regular text. Editing them in emacs' org "mode" makes certain text plain text elements behave dynamically (like cycling through or folding parts of an outline open/closed, etc, and more). The emacs text editor is super robust & extensible so you see people talk about custom set-ups, configurations, and workflows (which is a feature not a bug!) so it almost sounds over-the-top & superfluous to a non-user. The hardest part of using it for a non-coder is probably not getting bogged down with all that you can do and trying to follow how experts are using it before fully understanding the basics.
