Habenaria seeds are dust-like and you can't see if they are segmented with the naked eye.
I agree that you should buy bulbs. Now is the time as mine are sprouting outdoors.
Later in the year you can try and pollinate your own blooms.
As for the "seeds" you have. Sprinkle them on damp sphagnum and bag. Keep moss damp. See what comes up!
