I've been using vim for 10+ years. The only commands I know are for saving, quitting, enabling line numbers and syntax. I'm sure 90% of the people in your statistics are like me.
I have met people who said they use vim for programming and don't know how to use commands like `%s` and `G` to do those basic things. I don't think most people understand how to use vim, and for those cases it's about the same as using any other editor with a find, and arrow keys and delete. That is, about as much an editor as any textarea in a browser.
If you create a vimrc, even an empty one, I believe you don’t have to enable syntax highlighting manually.
(The existence of a Vim config file disables Vi compatibility mode.)
