Well no, you don't. But there are numbers in FPS. For example, you don't know exactly how much damage a rocket launcher will do, but you know a rocket launcher in the face will kill them. So, in a FPS, there is an incredibly simplified style of playing. This is different for different games of course, especially with more modern games that have hitboxes where shooting them in the head does more damage than in the foot. But generally, you know that a sniper rifle hit to the head will kill, you know that six pistol shots will kill somebody, etc. Its just not quantified, but qualified when you see the person hit the deck =D.
