ELI5: Does one person have to lose wealth for another person to gain wealth?

Does the money that one person makes have to come from someone else's pockets? Is there only so much money to go around, or can we as a world create more wealth by working harder as a whole?

There's a huge difference between money and wealth. Take an example: suppose there are three people in a village, and each of them starts with $2. So there's $6 total in the village. 

John is a lumberjack and fells a tree. He sells the wood to Karen, for $1. 

Karen is a carpenter and makes the wood into a chest of drawers. She sells the chest to Henry for $2. 

John now has $3, and Karen also has $3. Henry has no money but he does have a chest worth $2. The total wealth in the village is now $8. Everyone in the village is better off than they were before: John and Karen have more money, and Henry has something he wanted. 

Next Henry will probably do something to earn the money back. Maybe he's a shepherd and sells Karen a sheep for $1. And again everyone is richer, even though the village only has $6 in cash to go around. 

Money is a medium of exchange. Wealth is created by labor.
