Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that all mutations are harmful to an organism?

No. Multiple sources state that mutations can be beneficial or neutral as well as harmful, and one genetics article explicitly notes a small percentage are helpful and some inconsequential. This directly contradicts the claim that all mutations are harmful.
