As opposed to “behaving like discrete particles” Neither statement claims that electrons form a fluid or move through a solid as particles they simply say that when thinking about charge behavior in either of these two regimes, one’s intuition of particles (or a fluid) can be useful. It’s no different from photons: nobody claims they are an actually absolutely particles or waves (or exclusively one or the other) but rather that one can reason about them using either wave or particle mechanics depending on the situation.
