Could i get a six pack? Even though im...?

Ummm...im really chubby im 180 5'4.5 and 12....I do about 100 sit ups everynight, including a healthy diet- Breakfast- Oatmeal Lunch-Tuna Samwich with Clelery Dinner-Fish with Asparagus and carrots..i drink around 80oz of water. I run for 20 minutes everyday.I plank and lift weights. I just would like to know if i could even get a six pack with my weight...is it even worth the trouble?
