Its a bit difficult to tell because in the second picture your nipples are sortof "hard" unlike in the first photo, and so it sortof just looks like fat - but because of their shape in the first photo im thinking that you do have it due to the pointyness. Try squeezing the pointy part a bit (with your thumb and index finger behind the areola) and see if you can feel something pretty hard and bumpy/fibrous. Thats usually a good indication that it is. To help lean over and hunch when you do this so the skin loosens up a bit and you can get a good grip. You have some chest definition in the first photo so and dont look very overweight. Fat boobs tend to look saggier than that, while gyne when its not way out of control looks more "perky" especially if you arent very overweight.
