Yes lots of things just have to be unlearned rather than learned. I think that falsetto, withc, martian things are just ways to play with the voice, see what it can do. The falsetto trick is based in part on one thing, I believe. If you are speaking at a low pitch, the vocal chords are swinging completely, there is a lot of mass involved. at a high pitch, there is more stretch and the mass does not swing. For many people there is a noticeable shift between those two modes, sometimes people refer to it as chest and head voice, but that is only partly true I think. So the falsetto method kind of tries to bring you into that stretching-based sound. And then lowering pitch will bring you to a point where the mass wants to come back into play. Now a good voice it seems is if both can be blended together. Thats the theory as my therapist explained it or rather as I understood it. If you do not have that break, see if you can find it somewhere hidden - in a lower or an higher pitch - usually it is not within the normal speaking range. If you still dont have it, maybe your singing just made you already have it go away, then that is quite good, then you should be able to control your voice better already
