All the the bugs cannot be found. Really, at no time can any developer say that a game is bug-free.

Some bugs are deferred. One of the biggest things I had to get over as a tester was the fact that many bugs are known about but considered acceptable until the next patch. The producers (or however it is done at Blizzard) have to decide which bugs must be fixed (an easily reproduced crash) and which can wait for a patch or three (a text bug). Sometimes a crash that is difficult to repeat will be deferred and then it will turn out that players can repeat it just fine.
I think that one of the hallmarks of a great game is how few of the lesser important bugs you find while playing. Text bugs, for example, are so rare among the huge number of quests in WoW
