Correct. Chronicle makes it very clear that the Light and Void encompassed all of existence, and the coalescence of magics that resulted from their clash formed the cosmos as we know it. No matter how outrageous you believe it is, this is what was established in the books originally designed to be the definitive compilation of Warcraft lore.
The "titan's perspective" excuse that Blizzard came up with later was to give themselves the freedom to make changes while claiming the titans were simply incorrect (and therefore not invalidate the books), but they're ultimately retcons and there's no point calling them anything but.
