A mole is defined as the amount of substance that contains as many elementary particles(atoms,ions,molecules) as there are in 12g of carbon-12 atoms.
One mole of any substance contains 6.023*10^-23 atoms.

I also found the concept of a mole hard but it's really just a unit measurement, think of it like 1kg - there are 1000g in 1kg
similar to a mole - in one mole there are 6.022x10^23 atoms - its really useful for finding masses, Mr, concentrations and volumes of solutions and substances in chemistry
