"Low level" is relative. The article says that there doesn't exist any "low level" languages that programmers can use, this isn't a very helpful definition. If we go by the languages that programmers actually have access to, then machine code is as close as you get to the metal, and C maps very well to machine code. So by any reasonable definition C is a low level language for programmers. For a hardware engineer who works on CPU architecture it is of course different, but we are talking from a programmers perspective here.
