I know Transform is used to get position, rotation and scale of an gameobject but what does transform do?

{
    public Transform player;

    private void Update()
    {
        transform.position = player.position;
    }

}

here Transform gets the position, rotation and scale and then stores it in the variable player. I also understand that from the line "transform.position" that it is used to convert the position to player position but is that the only use and am I right about this?

Transform is a type, and is described in the Unity Documentation as

Position, rotation and scale of an object. Every object in a Scene has a Transform. It's used to store and manipulate the position, rotation and scale of the object. Every Transform can have a parent, which allows you to apply position, rotation and scale hierarchically. This is the hierarchy seen in the Hierarchy pane.

Every C# script that inherits MonoBehaviour in Unity will have a transform. Inherting MonoBehaviour will allow for a script to be attached to a GameObject in Unity. The MonoBehaviour class has many fields, one of them is the transform field, which has the type of Transform. The Unity Documentation describes the field as

The Transform attached to this GameObject.

Every GameObject has a Transform component, meaning that every Unity script using MonoBehaviour will have a non-null field called transform.

If your script is attached to the player GameObject, then there would be no need for you to store a reference to the player, and could instead use the transform variable.

Transform is a class in UnityEngine while transform is a property of type Transform from the GameObject attached to the script.
