Does 8 min abs workout on youtube also help burn fat?

I am 5 foot 1, 108 pounds and 13 years old. I have a small small small layer of fat covering my abs. Would this workout help reveal them if I did it ten times a day and kept a steady diet. Or does this workout only strengthen abs and not burn fat? How long do you think it would take to see results if I do this workout ten times a day? Do I need to do cardio with it?
