The code is below, I checked if i did anything wrong from the tutorial but as i can see i have not i even copy/paste the code they give with every video.

Thank you if you can help me & sorry if in wrong part of unity forum.

2. using UnityEngine.UI;
3. using System.Collections;
4.  
5. public class PlayerController : MonoBehaviour {
6.  
7.     public float speed;
8.     public Text countText;
9.     public Text winText;
10.  
11.     private Rigidbody rb;
12.     private int count;
13.  
14.     void Start ()
15.     {
16.         rb = GetComponent<Rigidbody>();
17.         count = 0;
18.         SetCountText ();
19.         winText.text = "";
20.     }
21.  
22.     void FixedUpdate ()
23.     {
24.         float moveHorizontal = Input.GetAxis ("Horizontal");
25.         float moveVertical = Input.GetAxis ("Vertical");
26.  
27.         Vector3 movement = new Vector3 (moveHorizontal, 0.0f, moveVertical);
28.  
29.         rb.AddForce (movement * speed);
30.     }
31.  
32.     void OnTriggerEnter(Collider other)
33.     {
34.         if (other.gameObject.CompareTag ( "Pick Up"))
35.         {
36.             other.gameObject.SetActive (false);
37.             count = count + 1;
38.             SetCountText ();
39.         }
40.     }
41.  
42.     void SetCountText ()
43.     {
44.         countText.text = "Count: " + count.ToString ();
45.         if (count >= 7)
46.         {
47.             winText.text = "YOU WIN!!!";
48.         }
49.     }
50. }

 

Have you checked your camera position? If it is on the opposite side of the ball then the movement would appear to be the opposite to what you are pressing.
