The word "mole" is short for "molecule."

Things would be very easy if "1 mole" of a chemical meant "1 molecule" of that chemical.

Well, it's almost that simple: "1 mole" of water (H20) means 6.022e23 molecules of H2O. (Here the notation "e23" means multiply by 10^23).

So instead of 1 mole meaning 1 molecule, we have 1 mole equals 6.022e23 molecules.

If I have a dozen eggs, how many eggs do I have? 12 eggs.

If I have 1 mole of eggs, how many eggs do I have? 6.022e23 eggs.

Like the word "dozen," a "mole" is just a count of something. It's intended to count molecules but could count anything.
