What does „complete” mean?

It means that no natural number can be added to {0, 1, 2, 3, ..., ω}

Duh, the set of all natural numbers N contains all of them.

With which numbers do you describe the sizes of N and N_0?

Most of them are dark and cannot be used as individuals.

Not their elements. I was asking for their number, how many
of them there are.

 There's a number of them, however, how many there are is not a number.

Either there is a complete and fixed set ℕ with a fixed number |ℕ| of elements.
If so, then 0.999...*10 = 9,999... where the number of nines has not changed by more than 0.
Or this is not the case.
But assuming completeness and simultaneously claiming different numbers of nines is stupid.
