Okay, so imagine there's a really big house called Anjou. And inside this house, there are different people who live there and they have different titles.
First, there are the counts of Anjou. They're like the people who are in charge of taking care of certain parts of the house. They make sure everything is in order and everyone is safe.
Then there are the dukes of Anjou. They're like the kings of the house. They have more power and influence than the counts. They make big decisions for the entire house and people usually listen to them.
So basically, the counts and dukes are just different levels of important people in the big house of Anjou. They each have their own jobs and responsibilities, but the dukes are higher up on the totem pole than the counts.
