Nucleons refers to both protons and neutrons, hence, it also refers to the atomic mass.

Since atomic species A and B have different number of protons but same atomic mass (nucleons) we can conclude that A and B are isobars.
For example, Calcium and Argon.

40 Ca 20, 40 Ar 18

On the other hand X and Y are of the same element (since they have same number of protons) but has different number of nucleons (or atomic mass) they are isotopes.
For example Deuterium and Tritium

2 H 1, 3 H 1.

Hope your doubt is cleared now...

Explanation:

The atomic species A and B have the different number of protons but the same number of nucleons. These are isobars.

Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. The number of protons in a nucleus determines the element's atomic number on the Periodic Table.
