Why did we use "\s" and not just a simple " " (just a space)?

Shouldn't we use just a space " " instead of whitespace? I tried the regex with whitespace on regex101.com and it also matches the telephone number if I press enter instead of space (meaning writing the telephone number on two lines).

I know this case might be basically impossible in a form, but still I think a space is better.

Honestly, I don't think there's a good reason for using the \s in this regex. In fact, the instructor states that he's putting in a space when he puts in the \s, so I agree with you that a simple space is appropriate here.
