Morphology

third + party

The meaning 'a person or group besides the two primarily involved' is directly and compositionally derived from 'third' (an additional/ordinal) plus 'party' (a participant or side in a matter). This adjectival+noun combination follows a common and cross-linguistic pattern in legal/transactional contexts, so a B1 learner who knows the constituent meanings can infer the MWE.

Etymology

Third party comes from the simple image of counting people: if two people are involved, anyone else is the third party. So it means a person or group who is not one of the two main sides.
