This is what you see when you click EDIT:  Help:VisualEditor

This is what you see when you click the arrow, then Classic editor:  Help:ClassicEditor  What they are showing in the article is only about the Visual Mode of the Classic editor. I don't think they have a good explanation of Source Mode of the Classic editor. In Source mode you work with Wikitext - see Help:Wikitext

All three are useful:

EDIT button "Visual Editor";  Classic Editor Visual Mode; Classic Editor Source Mode.
