For those that don't know, minutes are a measure of angles. One minute of angle is roughly equal to 1in at 100yard distance. So, 33 minutes is quite a substantial change at this distance.

In this case, it's just a measure of time. Dimorphos is in orbit around Didymos. This is why it was chosen as a target, because we can very accurately measure the difference in the length of it's orbit before and after collision.

No, 33 minutes is 1980 seconds, because the article is specifically referring to the orbital period.

TIL, I was under the impression it was the degree of change in the orbit not length of time to orbit.

The shape of orbits are not measured in minutes, there are multiple variables.
