Question about calories and alcohol

I have about 10 shots a day and have noticed significant weight gain and just looked up that shots have around 100 calories. This shocked me because thats 1000 extra calories a day and I didn’t even know. My question is if this data is correct, and when I quit, will there be noticeable weight loss? I’ve had people tell me that the weight on my abdomen could also be water weight from dehydration, and ascites. I don’t know though because I’ve only been drinking this way for ~8 months.
