Do we know if this experiment was a success? We're they able to change it's trajectory?

Of course we changed its trajectory.  That's simple physics.  It'll take a couple months of careful observation to see exactly by how much.

Did some back-of-the-napkin math:

a 566.9905kg spacecraft impacting a 5x109 kg asteroid at 6500m/s would impart something like a 0.737mm/sec change in the asteroid's velocity.

Does that include it's speed, gravity and the other object it was orbiting? There's more going on here.
