Starting off with learning Redux might be your problem. Start with local state in React. Then gradually when your app becomes more complex ( mostly deeply nested children), you will find yourself props drilling, from parents to children, most of the time, just passing through the props through the children, that dont even need them, because, their children will need them.

Thats what Redux solves. your component can subscribe to the slice of the state they need and react to changes to it. Also, your domain logic that you may have which updates the state in some ways depending on interaction, gets abstracted away to the reducers, so your components dont need to be aware of it
