Getting in shape, all things being equal, makes you sweat more, not less, since you are training your body to sweat more in response to the greater thermic effect of more intense exertion.
But it isn’t cooling (eccrine) sweat that causes pit stains. It’s apocrine sweat that’s released under stress. I don’t think that increases when you get in good shape. Probably decreases with your cortisol.

Adding to this, It raises your metabolism so you burn hotter just generally during the day whilst doing nothing too
Well shit, time to get out of shape then. 😉
Being fat retains heat and causes sweating too so you have to be out of shape but thin.
