A truly level playing field isn't even possible in theory.
In order for the world to be truly equal, everyone would have to look exactly the same, have the same IQ, the same aptitudes across the board, be raised the exact same way, etc.
Basically we'd all have to be clones of each other in a completely stagnant, monolithic global culture under a one world government that ensures all resources are divided equally. Even then it wouldn't be a fair playing field as you'd still have things like accidents, cancer, and other potential "bad RNG" events.
I'm not even sure you could create a level playing field even if you were a literal god creating a universe from scratch provided said universe was finite and bound to the laws of physics and you were creating multiple sentient lifeforms.
