I have a question for people 16 and up?

i am 13 years old and 5'0. My dad is 5'7 and my mom is 5'4. I am not chubby but i have stubby and sorta fat legs. Was anyone ever like that at my age and worried about what they would look like when they get older, and has anyone suprisingly became long and skinner by the age 0f 16 and up?
