Feathers in normal oviraptorids' arms aren't as pronunciated, and don't cover the whole arm. Plus, the hands of a bird don't have claws (except in the case of hoatzin chicks), and they aren't developed to act as the hands of paravians. Think of the relations between the two as those between a human's hand and a bat's wing: both are hands, but the former's has evolved to manipulate objects, while the latter's has evolved to become wings.
