Comparing your individual 1.0 to (total number of all player kills) divided by (total number of all player deaths) says that your deaths are average as compared to all deaths. It is not a measurement of player performance and can not be used to determine whether any individual player is average (or above or below average). It is a metric of deaths, not players. I'm sorry if you can't understand that but I can't think of a better way to explain it.
