How do you tell apart different notes in a fragrance?

I’ve only recently got into fragrances, my current collection is around 6 bottles.

I often see people writing in comments on fragnatica or here on reddit how they smell a fragrance and then pick different notes from the smell.

Is it a skill that you get with time as you smell more and more fragrances or it’s just something that your nose either can or can’t do.
I can smell a fragrance and tell if it smells good to me or not, but no way in hell I can tell if it has lavender, pepper or bergamot.
