They are the same physical device. "Inductor" is what it is;
"transformer" is what it does. A transformer is an application for an
inductor with 2 or more coupled windings on the same core.

Low *DC* currents. In the context we are discussing here (inductors in
AC circuits), there is no need for a gap in the core.

The inductance of a transformer's windings are not particularly
important when it is used as a transformer. It works as long as it has
"enough" inductance to limit the current to a reasonable value when
operated with no load on the secondary, and "enough" core so it doesn't
saturate in a single AC half cycle.
