using System.Collections.Generic;

public class Sensor : MonoBehaviour
{
    void Start()
    {

    }
    void Update()
    {
        if (GetComponent<Fruit>().transform.position == GetComponent<Move>().transform.position)
        {
            Destroy(GetComponent<Fruit>().gameObject);
        }
    }
}

Answer 1

Well, you do not have all three components on the object Sensor+ Fruit+ Move.
Then, even if they exist, their position will always be the same, because this is the same transform for all.
P.S. GetComponentin Update, yes, you should start with guides

Answer 2

Where's the error? And I realized that the 2nd script knocks out an error on line 26
