Indeed, a trumpet has one slide for tuning only and two more slides that are used while playing, so it's not even technically correct.
Your trumpet maybe, but my trumpet from 1957 only has tuning slides, which cannot be used while playing.
Yep. A basic trumpet has more slides than a basic trombone.
