Mastery refers to the upgraded version of a crafting, gathering or weapon skill. There's a mastery skill for all melee weapons and the bow which unlocks at level 75 skill for each weapon.
There's also mastery for gathering and crafting skills. The gathering skills requires 75 skill to unlock the mastery and it is simply an enhancement to the skill which makes your success rate higher and reduces the harvest time.
The crafting skills on the other hand unlocks at 100 skill and gives you the ability to make high ranking armour and weapons.
