Is there a certain condition you need to meet in order to obtain any riven from sorties, besides having free slots and completing TWW?

I've been running sorties for like 2 months without getting a single riven. I really want to persuade myself that this is pure RNG but this probability as a common loot is starting to make me doubt my statistics class...
