What it means
There is nothing below it. An atom needs at least one proton to be an element at all, and hydrogen has exactly one, with a single electron to balance it. Everything heavier was built out of hydrogen inside stars. It is also the great majority of ordinary matter in the universe by count of atoms, which makes the simplest thing in chemistry also the commonplace one.
