ELI5: What is the difference between the roles of a Director, Producer, and Studio, in the making of a movie?

Director makes the artistic decisions; who plays who, how shots get taken, what the edit looks like.

Producers do the heavy lifting on the organisational side; contracts, locations, etc

Studios put up the money. Producers may well be involved in negotiating other income streams as well.
