The atomic mass of an element is the average of its isotopes, weighted by abundance in nature.
The characteristic of an element that represents the average mass of its isotopes is called the atomic mass. Atomic mass takes into account the abundance of each isotope of the element and is typically listed on the periodic table as a weighted average.
The average atomic mass is a weighted average of the masses of all isotopes of an element, taking into account their abundance. The atomic mass listed on the periodic table is the weighted average of all naturally occurring isotopes of the element. So, they are essentially the same thing, with the average atomic mass being a more specific term.
Isotopes have a different amount of Neutrons. The atomic mass is the sum of Protons and Neutrons. Therefore having a different number of Neutrons makes the atomic mass greater. Or vice versa. Boom. Solved.
The atomic mass of an element is the weighted average of the masses of its isotopes, taking into account their abundance. If the atomic mass of an element is 197.97, it represents the average mass of all naturally occurring isotopes of that element.

the atomic mass
The weighted-average mass of all the known isotopes for an element is called the atomic weight or atomic mass. It is calculated by taking into account the abundance of each isotope and its mass to determine the average mass of all isotopes present in nature for that element.

There is an average atomic mass because all atoms of the same element do not have the same amount of neutrons (isotopes), therefore variations in atomic mass exist. The average atomic mass of an element is the estimated average of all the atoms of the same element, given the average of different isotopes in a scientific sample.
The atomic mass of an element is the average mass of an element's isotopes, weighted by their natural abundance. It is expressed in atomic mass units (u) and is often close to the mass number of the most abundant isotope of the element.
