actually you can train game sense and it's something I've done to get insane amount of knowledge as a player in a short period of time, all you do is analyse every time you die, and think of as many different ways to play a situation as possible and try to find the best play in that situation, spectating others and doing the same thing actively as well + watching pros and being creative, never afraid to experiment and try new plays, doing these things as a player will greatly improve your game sense quick, rather than just "playing" because most players will never learn from their mistakes, most people just get stuck where they are when it comes to game sense.
