You are right, oil paints 'dry' by oxidation. Before using oil-paints, it is a good idea to read up a little about the practicalities of their use. There is also a plethora of medium that change the behaviour and properties of the basic oil-paint as it comes out of the tube. This is not the place to write a treatise, so I would really advice to read up on this and to not rely solely on YouTube modellers' video by people who may be knowledgeable or not.
In general, when you apply 'lean' washes, i.e. oil-paints highly diluted with a solvent, typically a turpentine substitute these days, they dry faster and more matt. There are also so-called 'drying oils' that contain oxidising agent and thus speed up the process. In general, I would expect to wait for several days between washes in order to make sure the process of oxidation is well advanced, reducing the the risk of smudging of earlier work. Leaving the model in front of a window to absorb UV-radiation also helps.
Some traditional artists' paint suppliers, such as the Spanish Vallejo, have branched out into the modelling realm with their products. Thus one should expect that their products are of good quality (which I can confirm for Vallejo's acrylics).
