I wonder how many people actually flip a coin more than 5 times in their lifetime.

It's me and every other math teacher, teaching the statistics of coin-flip.

Here is Kristy Perrin, who lost her cricket team's coin toss 35 consecutive times, before breaking the streak. That's one in 34 billion. https://www.netballscoop.com/old/forums/topic/meet-kirsty-perrin-crickets-biggest-loser/index.html …

That is absolutely amazing!. Are there any videos on the internet from Kristy breaking the streak?

Assuming that everybody alive has flipped a coin twenty times. Not entirely sure if that works well for the entire world population.

Some people don’t have access to coins.

Wrong and/or badly stated. If X~Bin(20, 0.5) then P(X=20) = 0.0000009537. Which if you apply to the entire human population implies 7,200 people, but only if you assume every living human has attempted to flip a coin 20 times.

(0.5^20)*(6.8*10^9)=6485, almost accurate

You are correct, this would increase the result to apx. 7200
