I think by its nature, if you don’t care about the lore then you don’t need to care about the lore.
For me, I ask questions about why X is the way it is, why are there Y monsters, and look for internally consistent explanations for things in the game. If the explanations aren’t there, then I don’t enjoy the game as much as I might otherwise. Because of that, I like lore in games.
It sounds like these things don’t bother you. So you’re probably fine. 
It won’t really hold you back much (if at all) to ignore it.
