correct me if i made a mistake

“To make things worse, many problems do not allow for precise mathematical models to be defined, but they can be described only through extremely general concepts, whose instances are characterized by high variability.”

It means “as we can not define a precise mathematical models it make things worse but we can described them through general concepts whose instances are characterized by high variability”?
