The inductances of the transformer is just a wild guess, so the oscialltion frequency is also. I am attaching a screenshot of the analysis I ran of it. But in any case, LTSpice says your circuit works. Oscillators are tricky circuits, and in my opinion their designers are magicians (especially those YIG oscillator guys). You might also think of the transformer as the feedback path that provides the necessary phase-shifted feedback from the collector (output) back to the base (input). This PDF document includes all the necessary details, such as product overview, features, specifications, ratings, diagrams, applications, and more. That phase shift is what causes the circuit to oscillate.

In this circuit I suspect that phase shift is the most important feature of the transformer, allowing the collector and base to see the same voltage vs. But it would couple the two sides of the circuit, while providing a phase shift between them.
So you are right, this transformer would not boost voltage. This type of transformer is often called an isolation transformer. But a transformer can have an equal number of windings in the primary and secondary, in which case it does not increase or decrease voltage. Confusion arises because common transformers step voltages up (or down). 2N2222 Datasheet : NPN switching transistors / 2N2222 Datasheet, 2N2222 PDF Download Philips Electronics, 2N2222 Datasheet PDF, Pinouts, Data Sheet, Equivalent. So while your component isn't "an inductor", it is "two inductors". Of course, a transformer is just two inductors with linked magnetic flux. Also, the dots and dashed lines indicate "transformer". Since this thing has four terminals, it can't be an inductor.
First, an inductor is a two-terminal electrical component.
