Cool the concept of mole

i need to get the hang of the mole concept that , 1.008 g of hydrogen constitutes 1 mole atom, whereas 12g of carbon constitute that 1 mole atom! does it mean that these amounts for H & C contains the Avogadro number of atoms??
does it imply the hydrogen is more denser (or heavier or something crucial) than the carbon as it needs to be only 1 gm of it to be 1 mole?? why does this difference in mole amount (of grams ) happen??

First, one mole is just like a dozen or a thousand. It just means that we consider a specific quantity, 6.02X10^23. So if you have 2 thousands eggs it means you have 2000 eggs. If you have 1 mole of atoms, it means you have 6.02X10^23 atoms. You can see that with the same number of atoms for 1 g of hydrogen and 12 g of carbon. Then it means that each single atom of carbon is heavier
