Hydrogen != water.
They are WRONG, not RIGHT.
Earth's atmosphere is indeed primarily composed of nitrogen, but that is quite a bold claim to say that that Earth as a whole is primarily composed of Nitrogen. I am under the impression that the metallic rock in the core and the mantle is much greater than the nitrogen, both in terms of volume and mass. Where did you read that earth as a whole is primarily composed of nitrogen? The Australian museum says:
The overall composition of the Earth is very similar to that of meteorites, and because of this, it is thought that the Earth originally formed from Planetesimals composed largely of metallic iron and silicates.
