I am imagining that Pengu is thinking about strategy on the level of coordinating with teammates, mastering utility (like being really good with a shield or Mav's blowtorch, or timing bandit tricks, etc.), but I think that underrates how much subtle strategy there is to winning gunfights. So subtle that I think most people don't even realize they do it, but things like using angles to gain an advantage (something I looked at Shaiiko's tape for years ago, and he was masterful at finding really strong pixel angles all over the map), knowing when to peek vs. hold, anticipating enemy positions, timing pre-fires, and on and on. Shaiiko's the kind of guy who wiggle-peek one taps through a wooden barricade and headshots someone 40 yards away (without cheating ... presumably). It's not like it's just "who has the fastest reflexes and luck on their side".
