A tilt needs a reference plane
An orbit has no reference-free numerical tilt. JPL’s heliocentric glossary uses the ecliptic; satellite work can instead use the orbiting body’s equator.
An orbit’s inclination to Earth’s equator generally differs from its inclination to the ecliptic. Comparing unlabelled values can mistake coordinate choice for a physical difference.
Equatorial, polar and retrograde motion
With the usual planetary-equator and rotation convention, i=0° is a prograde equatorial orbit, 90° a polar orbit and 180° a retrograde equatorial orbit. Direction conventions are part of interpreting the angle.
A polar plane passes through the pole directions while the planet rotates beneath it, exposing successive longitudes. Complete mapped coverage still depends on instrument swath and orbit design, not merely one revolution.

Inclination does not specify all orientation
Two orbits can share an inclination while crossing the reference plane at different longitudes. Ascending-node longitude supplies additional orientation; ascending and descending crossings go northward and southward respectively.
Inclination also leaves size, shape and current position unspecified. Other elements and phase are required, and perturbations can gradually precess an orbital plane.
