No it isn't. Near the poles, there's over 10 BILLION metric tons of hydrogen. Even the soils elsewhere contain from 10 to over 100 part-per-million of solar wind implanted hydrogen.

There's plenty of hydrogen on the Moon for whatever purpose we would need it -- from water for life support to liquid fuel for rocket propellant.
