Yes that is the standard language in the field. It does not refer to the number of marketed products. Look up the number of novel drugs approved by the FDA per year. It only recently exceeded 40 per year, and the FDA has not existed for very long.
if we consider that you are not making things up(which I am very not confident), then your link is useless in this discussion, because it doesn't give a sense how many non-protein targeting drugs were approved by FDA.
