Yes. The first 4 plus RansomTime's #2 are definitely "5 things every serious user should know."

I think of the title as being incomplete, with the full version being "Five Things Every Admin Should Know... so if you don't, then you shouldn't be an admin".

Although there's probably at least 20 things every admin should know, including RansomTime's 5.
