Of the [47] cars, there are 2 more A that can help me and [45] that wont, so would the odds of hitting trips on the turn be [45:2 (22.5:1)]?
Yes, you have the concept. I corrected your math to reflect a 52 card deck.
This is the same as "counting outs". How many "outs" do you have to improve your hand? In this example, 2. So you have 2/45th chance to improve your hand next card.
