So how should I interpret these? Hit the Os but avoid the Xes?
Yes. But avoiding the Xes at all cost is not always necessary - they may disappear in the general noise. Depends on the chord. If it doesn't sound bad then don't worry. It'll become easier with time in any case. Is it acoustic or electric? For electric guitars you mute the string(s) instead of not playing them - with the heel of your right hand, or a finger on your left, or some other way - players have their own ways (on electric guitar it's much more important to mute those strings. On acoustic you can mostly get away with not doing it.)
