The difference between dune and desert
Dune is a mound or hill of sand piled up by the wind. Desert is an area where the annual precipitation is less than 250mm, or an excess of evaporation over precipitation, and is consistent with sand, gravel, and rocks.
Therefore, even if the surface of the dune apprears to be dry, wet sand soon comes out when it is dug. On the other hand, desert evaporation exceeds precipitation, only dry sand comes out even if it is dug.
