It's that it's not 10% of racoons have rabies, but 10% of the ones that expose people to a bite scratch etc. The reason the numbers aren't the same, significantly less than 10% of them have rabies, is mainly that rabies itself can make them more hostile etc., on top of if bitten by a racoon that is more symptomatic seeming you are much more likely to get it checked out.
