There's some truth to what the gp said. Some hydrogen will escape, enter the upper atmosphere, and be blown away by the solar wind and thus be permanently lost.

I assume that this has been happening to all gases in the atmosphere for aeons, and thus, while technically correct, it is completely negligible for the relevant time scale.
