Simple Dice Game - Error with Variable within an Instantiated Game Object (Prefab) - CS0118 and CS0119 Errors

Hello Unity Community! Trying to make a simple dice rolling game with two players.

I have an empty game object with the PlayerSetup class attached. The purpose of this script is to create a prefab for each player (2). The prefab has a class attached (as a component) called PlayerDice - within this script it calls the DiceRoll class for each dice that is rolled.

What I am trying to do is pass a value through to the PlayerDice class and change the value of the numDice for each prefab. However, it throws me two errors:

Assets/Scripts/PlayerSetup.cs(31,32): error CS0118: 'PlayerDice' is a 'type' but a 'variable' was expected

Assets/Scripts/PlayerSetup.cs(31,32): error CS0119: Expression denotes a 'type', where a 'variable', 'value' or 'method group' was expected

So clearly something is wrong, I just don't know what. Any thoughts/help? (Below is my code snippets

 public class PlayerSetup : MonoBehaviour {
 
     Dictionary<string, int> _PlayerSetup = new Dictionary<string, int>();
 
     public Rigidbody playerPrefab;
 
     void Start () {
         //Player Setup
         _PlayerSetup.Add("Chad", 4);
         _PlayerSetup.Add("Bill", 4);

         //Position is not necessary, just doing it for fun
         float x = 5;
         float z = 5;
 
         //Cycle through the dictionary of players, create them off a prefab
         foreach (KeyValuePair<string, int> item in _PlayerSetup)
         {
 
             Rigidbody playerInstance;
 
             playerInstance = Instantiate(playerPrefab);
             playerInstance.name = item.Key;
             playerInstance.GetComponentInChildren<TextMesh>().text = item.Key;
             playerInstance.transform.position = new Vector3(x, .5f, z);
             playerInstance.GetComponent(PlayerDice).numDice = item.Value;
             
             x = Random.Range(-5, 5);
             z = Random.Range(-5, 5);
         }
     }
 }

 public class PlayerDice : MonoBehaviour {
 
     public int numDice = 1;
     Dictionary<string, List<int>> _PlayerResults = new Dictionary<string, List<int>>();
 
     void Start()
     {
         //Create a new dice roll
         var dice = gameObject.AddComponent<DiceRoll>();
         
         var diceResults = new List<int>();
         int num = 0;
         int x = 0;
 
         //Rolls a 6 sided dice for each number of dice the player has, stores it into an array
         while (num < numDice)
         {
             x = dice.RollDice(6);
             diceResults.Add(x);
             Debug.Log("Dice roll: " + diceResults[num]);
             num++;
         }
         Debug.Log("Highest Roll: " + diceResults.Max());
         
         //NOTimplemented yet - I need to pass the item.Key (player name) value through...
         //_PlayerResults.Add(item.Key, diceResults);
     }
 }

 public class DiceRoll : MonoBehaviour {
 
     public int RollDice(int diceSides)
     {
         int result = Random.Range(1, diceSides - 1);
         return result;
     }
 }
