Past Riddle #85 (Feb 5, 2024)

I'm not seen, but I do exist, I mark every moment with an unclenched fist. In your grasp when you're young, slipping as you grow, I dance on the edges of memory's glow. Kings and paupers, to me, are the same, For I am the player in life's fleeting game. What am I?

Stats & streak won't change.
