As to how they can all be different- think about a basic cake recipe- a little more of this or that can change the whole nature of the cake! More butter and less liquid will get you cookies, or add more of a flavor (chocolate or lemon) and it's a totally different cake.

Cannabis is the same way. The basic recipe is there, but each plant has its own variation on the recipe. THC and CBD aren't the only "ingredients". There are at least 66 natural cannabinoids identified so far. That's a lot of "ingredients" to play around with.- Granny:hippy:
