I'd recommend Beyond Infinity, by mathematician Eugenia Cheng. It nicely explores this topic.
We are not talking about the hierarchy of infinities here, since both sets are countable infinities - as you pointed out.
But even countable infinities have scale. Picture 2 sets, defined as follows:
a = {n, 0 < n <= ∞}
b = {1000n, 0 < n <= ∞}
Simply, we have a - a set of all integers, and b - the same set with a multiplier attached
It is easy to see that for any given value of n, b will always yield a larger result.
So although if were to take the sums of a and b from n=0 to n=∞ we would find both sets to be infinite, set b is said to be a larger infinite set than a.
For an even lighter read but still good check out Eugenia Cheng's books... (and YouTube videos)...
