Question about the use of score inside of the Player component

I just want to be 100% sure about this.

In the player component we have compose another component which is the Counter component.

we add the <Counter /> component "score= { props.score }" because without this we won't get the actual score that is inside the actual Counter component here:

function Counter(props) {
  return (
     <div className ="counter">
        <button className= "counter-action decrement"> - </button>
        <span className="counter-score">{ props.score }</span>
        <button className= "counter-action increment"> + </button>
      </div>
  );
}

we have to give the Counter component at the Player component this prop as well because only in the Player component we are Actually using the Counter component by calling him with the <Counter />.
