The immutable game mechanic dictates exactly 10 kills per completed round in Counter-Strike, irrespective of player count or round outcome. Given 10 is an even integer, the cumulative total kills across any BO3 series will invariably be an even sum. An odd total is a mathematical impossibility based on this foundational round-kill parity. This market isn't about team fragging power but basic integer properties. 100% NO — invalid if core CS2 round mechanics change to allow non-10 kill rounds.
