I just wanna lose my gut

The most critical part of losing weight is counting the calories of what you eat, so you know exactly what you have to do to lose the weight. One pound of body fat is equivalent to 3500 calories, so if you can manage to eat at a 500-calories-per-day deficit you will lose one pound per week (most people lose scale weight at a faster rate than this when they first start dieting, but this is water weight loss and won’t be maintained in the long term).

Will drinking less alcohol and fewer sweet treats put you into a 500 calorie daily deficit? There’s no way to know unless you start recording the calories of everything you eat on a daily basis.
