Wetting is a rather complex topic. Basically, yes.
Not all solids can be wetted. Wax, for example: water beads up on a waxed surface; it does not actually wet the surface.
Not all “wetting” involves water. Soldering and brazing involve “wetting” base materials with a molten filler metal. Dripping molten metal on the base material does not necessarily “wet” it either: the molten filler can “bead” just like water on wax. When it solidifies, the filler metal is not bonded to the unwetted base metal.
