Exactly. A theoretical plea deal in this case would be something like dropping the conspiracy charge and reducing the battery resulting in great bodily harm to simple battery. Happens all the time.
Is that what will happen in this case? Who knows. Kamara will almost certainly plea out, but beyond that, predicting a specific outcome at this point, with the limited set of facts we have, is a fool's game.
In any event, plea deals are an important part of the legal process (the 97% figure is pretty much spot on), and the system frankly couldn't work without them. The courts are already way overworked and simply could not accommodate every case going to trial.
