No models on table at the start of the game

I have been unable to find anything in the rule book about this. Google says without making a reference to a page that the game continues until turn 5 even without one side having a model on the table.

I ask this because of the Day of revelations and drop pod rites can make it so you have no models on turn 1 or deployment. Do you auto lose if you take all deep strike models with these rites?
