"Car" typically means "passenger vehicle" in common parlance, at least in the US. A lot of truck sales like you point to are fleet sales for work vehicles, so this person is probably pointing more towards non-fleet sales, where the RAV4 is indeed the top seller.
Also the RAV-4 isn't a car, it is an SUV.
