No that one definately is true. However there are times when one may look like another. For example, does walk on their toes and bucks on their feet... so you'll see the dew claws in a walking buck track as well as see the front "toes" often splayed open... however if the mud is really deep... or a deer was running, a doe track can look like a young buck track. But other than that its very easy to tell the difference by looking at the distance between the tracks, the shape and size of them, as well as the width of the shoulders (bucks have wider shoulders than hips, so the larger front tracks are usually set slightly to the right or left of the smaller hind foot, as well as in front of them a few inches). Fawns of course place their front and back feet in almost exactly the same spot.. so you get that double stamped look to their track.... however when they are fawns you cannot reliably tell gender by the track. Does tend to place their front and back feet almost together, but often in a straight line. And of course they walk on their toes and their toes are usually much much much closer together than on a buck track.

Sorry that got a little longwinded.
