Raise your hand if your twelve
Excellent answer.
A question usually answers itself, if we think in a step by step process, from first principles.
You ask to ask yourself, "How can a person answer this question?" What does it take?
For simplicity sake, we'll make the population of the world as 32 people, the number of chess pieces on the board. "All the world is a stage." We'll shrink the world into a small stage.
How would you answer this question?
Get a random 32 twelve years old chess players. Get the average rating. Then figure out where you are and whether that is good enough.
Why don't you do that in real life? Because that is the only way it can be done.
Ask yourself how you can solve your question.
I once asked myself
How many words are there in the dictionary?
What is the process of the answer?
1. Take the word on the word cover, "Over 50,000" entries. (no)
2. Start counting from "aardvark . . ." (No)
3. Pick out 10 pages randomly by throwing a decimal (10-based) dice. Count the number of words on each page. Average the number of words on 1 page, multiply by the number of pages.
In statistics, I took a random sample. That's how TV ratings work back in the days, by a small sample of Nielsen recording boxes on a TV.
Ask yourself, "How will the question be answered?"

3. Pick out 10 pages randomly by throwing a decimal (10-based) dice. Count the number of words on each page. Average the number of words on 1 page, multiply by the number of pages.
It worked amazingly well. I did it 3 times to see what are the differences. As I vaguely remembered, the differences are within 3%, negligible for only 10 pages.
A good enough answer for a sample of 10.

That is how you can understand society and history, which are made up of hundreds of millions of people. “All the world is a stage.” You shrink it down to a small number, 10 is good enough.
That is what movies do, tell a story in a allegorical manner. Enemy at Gates. You can tell the story of WWII on the Eastern Front from from an allegory of a duel between 2 men.
