Probably a stupid question about dunking

Right now I'm about 5'11 ish 175-180 pounds, planning on cutting for summer down to 165-170.

Here's the deal, I can jump up and hang on the rim fine, and I can hit the ball on the top of the rim, but can't really slam it in yet.

If I lose extra weight and fat, will I be able to jump higher?

It's probably an idiotic and obvious question, so sorry if I'm just stupid.
