im pretty sure if we put ice in a bucket of saltwater, it will be the same temperature as a bucket of regular ice water.

I agree. What will occur is that if you then put the bucket of saltwater in a freezer the saltwater/ice solution would stay liquid at a lower temperature than a bucket of ice water without the salt. In other words saltwater freezes at a lower temperature but salt does not magically make ice colder, it only makes it melt faster.

This is called freezing point depression. For that matter sugar will accomplish the same thing.
