Character speed changes with screen

Hey I'm working on game at the moment and just made my first build for fun.

but the moment i started moving i noticed that my charakter moved a million times faster than in unity. i dont know why that is though as im multiplying with Time.deltaTime and everything else should be fixed, right?

my code looks like this:

 public float thrust = 20;
 
 void Update()
 {
  Horizontal = Input.GetAxisRaw("Horizontal");
 
  rb.velocity = new Vector2(100 * Horizontal * thrust * Time.deltaTime, rb.velocity.y);
 }

here is a video of the changes
