you're really confused on some stuff. If you really want advice that's specific to YOU, post a picture. Otherwise it's hard to speaking in any terms other than generalities. If you want to gain MUSCLE, you still have to eat enough to support muscle growth. Muscle has weight to it. And the more muscle you have, the more calories it will take to sustain, and grow it.
The whole point about not bulking and cutting is that people tend to get EXCESSIVELY fat when they do this. What I suggested is that I can continue to grow without getting so fat that you can't see my abs. I've never been more than about a 31" waist size, at any point.
When I started lifting weights, I weighed about 125 lbs, and was the same height I am now. But now I weigh about 195. I was able to add 70 lbs to my frame, without ever losing my abs. It's not easy. It takes time. But it can be done.
