I then show you the lowest card I have. No matter what card I show you, you still don't know if you have the ace as I always have either a King or a Queen, the lowest of which I show you. So this gives you no new information and doesn't change the chance of you or me having the ace.
Since you are showing the lowest card you have, if you show a King, that would mean you also have the Ace, and therefore I have the queen?
Whereas, if you show a Queen, then you might have the King, and I have the Ace. Or you might have the Ace, and I have the King.
