Ah, definitions!
I would say that a counterstamp is a particular type of PMD whereby images and/or letters are stamped onto a coin by a die or a punch.
As opposed to random PMD, like drilling a hole or hitting a coin with a hammer, the counterstamp generally has a purpose-perhaps political, perhaps advertising for a company, perhaps someone's name for a memento or gift.
But like any definitions, there will invariably be gray areas where an item is hard to classify one way or the other.
Counterstamps can be applied at a mint but then by definition they are not Post Mint Damage, although they may look exactly the same.
