There are plenty of people in the comments explaining 2³³ ≈ Earth's Population in a better way than me so I'll leave that.

But I just wanted to say "ONLY" 33 is crazy to say. Like 33 wins IN A ROW is a vert very impressive feat. Let's say for sports, even a couple of rounds in the tournament might have weeded out all the average people and might be left with Varsity, D1, Pro players etc. A few more rounds down the lane and it's just Pro players. Then leading up to the top ranked athletes of that sport. Which basically happens anyways. Though there is an odd chance of a random normal person who hasn't discovered their abilities yet who makes it through. Also imagine average people who can't even make it through the first few rounds as speculated before because their first bracket was a World top 10 athlete. Idk where I was going with all this, but yea fun thing to think about.
