Bugs are a specific kind of fault, it could be that or they might think that any number of aspects (e.g. plot, ui, gameplay loop, animations, crafting tree, character progression, quest structure, world layout, etc, etc) are flawed in any number of ways.
As an example If someone says that modern ubisoft open world games “have a lot of faults” its unlikely they are complaining about bugs per se.
