In terms of being bigger obviously Zelda is Bigger the AC as a franchise as Zelda is a momentum changer and platform seller like Mario Kart and so on, AC has better sales but is not a platform seller as it's one of those games that sells to the userbase but not necessarily brings new people in.
In context of the thread I think he or she means life time sales.
