For AC at this frequency there is nil skin effect.


Not nil. Do the math.


Very much so as close to nil as it gets. Review the math.

I'm afraid you've got a pretty limited notion as to what "nil" would
be. Remember, with AC, one of the big concerns is the transmission
of significant amounts of power over long distances - have you thought
about how large those sorts of conductors ARE?
