So my question is if i mate a male pin to a female het ( caramel or axanthic) whats the chance il get a axanthic pin, or caramel pin? Or is that how it works
I do not believe that is how it works.

Recessive morphs won't show up unless they get that recessive morph from BOTH parents. Meaning that for an axanthic, for example, if you breed a het axanthic to a het axanthic, there's a one-in-four chance of getting an axanthic.

Breed a het axanthic to something that isn't het axanthic and you have a zero chance of getting a visible morph. Some of the offspring will be hets but there's no way to know which ones.

What you can do is this...buy an axanthic female, breed to your pin male to get 100% hets. Then breed one of the offspring that is pin to the female, and there's a 50% chance of getting an axanthic, and a slim chance of an axanthic pin.

I personally prefer incomplete dominant morphs myself, because I'm so paranoid about buying hets...but I'd love to get a pair of het clowns or het VPI axanthics down the road.
