"The largest available Minecraft world" implies we're talking about one world. Then "totaling 15TB" implies the world is 15TB large which would be incredibly impressive and potentially involve multiple shards of minecraft servers stitched together. But 15TB of world files means there's multiple copies of the same data. Still impressive but not the same as a single 15TB world.
