Basically, the model is the actual solid shapes, and when you first make a model, the whole thing is gray. The textures are the colors and patterns and whatnot. The characters' eyes are also textures that get moved around wherever the animator wants them to move (at least, that seems to be the case?).

You can see an example of this in Volume 2 Production Diary 2 where they talk about the process of taking Velvet's concept art and turning it into a 3D model and making the textures for it. They actually have a bit where they show you someone working on building and coloring the model for Velvet's battle outfit.
