Why is mapStateToProps needed if I can use the entire store in my component?

From definition

mapStateToProps is used for selecting the part of the data from the store that the connected component needs.

I didn't understand why do we even have to specify mapStateToProps if I can use the entire store data in my component, what exactly does mapStateToProps provides? What will happen if I select some part of data?

Any advantages?

mapStateToProps gives you only the parts of the store you need in the component.
It calls every time the store state changes (every time the relative part of the store that you return is changed).
It can return different structures of the store data
Can return different structures of the store data for different component props.
Can be re-used for different components that need the same parts of the store
