It 100% did. Any impact on any body will move it. The greater the difference between the two objects the less change there will be.
With a planet killer asteroid it will be much larger so a DART sized craft will change its orbit much less but it will still change it. So for such an asteroid we ether need to hit it years out for that tiny change to have time to propagate or we hit it with something with more energy.
