All right, I think I see your conceptual problem here. When you calculate the pot odds that you need, you are calculating the amount of outs that you have devided by the number of unknown cards. Those unknown cards include the cards that have been folded. For example after the turn there are 46 unknown cards (52 cards in a deck - 4 visible cards - two cards in your hand), so when calculating pot odds you divide your number of outs by 46. This calculation includes the chance that your outs have been folded.
