ELI5: How does Humblebundle work?
gpt
Each customer pays whatever he feels like, lets say 10 <insert currency here>. That amount is distributed among all of the game creators + some charities and and some money go to huble bundle itself. 

For the most part it's a win-win-win-win situation.

First win : you. You win by getting a butload of games for fraction of the cost.

Second win : the developers. This is sometimes not such a big win, but some bundles could generate 10's of thousands of (~65% of total sales divided by the number of developers in the current bundle) <currency goes here> for each developer for games which otherwise may not sell so well or to serve as a sort of a kickstarter to an upcoming game.

Third win : the charities. Charities like "Charity Water", get ~15% out of every purchase .

Fourth win : Humble Bundle by default they seem to get ~20% of each purchase you make.

N.B. Please take into consideration that all the estimates above might differ as you are able to change which party gets what amount of <currrency>
