Incorrect. See your quoted statement above. No limit to how far you need to go.
It is infinitely far from the first one, an infinite number of unit differences
separate them.
What is the difference between the 10th and 50th natural? Is it 40? What is the
difference between the 1st and the ooth? Is it finite?

If there are an infinite number of them, some pair of them has an infinite
number of steps separating them, and infinite number of elements whose values
are between their two values.

The naturals are each represented by a point on the number line. Ever heard of
the number line? Every distinct value is a distinct point on the number line,
each a distinct distance form the origin, where the value is 0. I am surprised
you have never heard of this construct. Perhaps you should try school or a
book.

The two points (whole numbers) that have an infinite number of points (whole
numbers) between them.

"What is space between two points on the number line? The difference between
the values of those two points. " Remember?

Are you talking to the mirror?

a is the origin, b is an element in the infinite set with an infinite index in
the set, that is, with an infinite number of elements between it and the
origin.
