The definition of 'exclusive' is pretty unambiguous. It means only available on one system.
But in the context of certain arguments, games available on one console & not on another is also relevant. Games like this are important when comparing the libraries of two consoles, since these games act as factors that differentiate between the consoles.
Let's say for example you're comparing the libraries of the PS3 and the Wii. Games like Grand Theft Auto, Assassin's Creed, and Red Dead Redemption, while not exclusives, still contribute to the PS3's library being better than the Wii's.
