I would have to guess that it's the total amount of cards in the deck. So, when you start the map, you have 40 options. As you progress through the map, your options will decrease (hence why you will see the number on the left side decreasing). However, there is a limit to how many of one type of card you can get.

So, to sum it up, it's similar to a regular deck of cards.
