What does avagrado number denotes? Number of molecules in one mole? But how can molecular mass of one molecule I.e one mole contain so many molecules?

Actually avagadros number represt nothing ,its just a number, Na =6.022×10^23, so i can jkin anything to it,like ole alway contains avagadros number of things,like when i say i hav 1mole of bananas i mean i have avagadros number of bananas .So when i say i have 1 mole of molecule i mean i have Avagadros number of molecules.And yes 1 olar mass of the sumbstance contain so many molecule!!
