You are correct.
It does say that.
However, you need to win the game to get the achievement. Why? I don't know. Maybe only winners count as registering game completion.

So you don't even want to play legit?

Okay, well then try this:

Make a game with 1 other person and an AI player, set on easy.

When the game starts, share all your info with your real life player, then use your cheating nigh omniscience to figure out which 6 cards the AI player has between the two of you.

You can get both achievements for both players in four quick games this way.


Note: Doing this in a real game is still cheating and you shouldn't do it because it's rude to others and ruins the point of the game. I do not advocate cheating in lobbies unless the entire group is participating that way as friends.

Not to my knowledge.

There's 6 tied to wins with a certain character, some tied to total wins, some tied to total dice rolls. All of these should be fairly easy to get from playing against other players online in general.

The friend achievements are the only ones I've found with a deceptive description.
