I'm guessing one would have to train in the art of using dust. Similar to avatar, how they have to learn how to bend(if the have the natural talent for it) the elements. It may be the same case for those in the RWBY world. Although if Dust can be should in shops and according to Monty, used in machinery and all the likes then my guess is anyone has the potential to manipulate it.
