Thats because not all parasites are capable of causing disease. Best example would be hair lice. While they live in human hair, causing frequent itches, they do not make their host ill. Fleas and bloodworms, while they are carriers of certain pathogens, are not pathogens themselves.

Also, the better way to look at it is through venn diagrams. In case the premise is not logical the next time you come across it.

Pathogens are parasites because they benefit at the detriment of the host; Namely by causing disease.

Not all parasites are pathogens, because a parasitic relationship is defined as one entity gaining at the expense of another.

If you do not cause disease you are not a pathogen.

One could argue a baby is a parasite as they take the resources from their parents!
