If a child was born with the ability to bend, it doesn't necessarily mean that they'll develop it. The creators (I believe) stated that Sokka had the potential to be a waterbender, but never looked into it. The process of children learning about their bending abilities is so far unknown, but we can assume that there is some way for adults to figure it out; Katara was known to be a waterbender when she was very young, and Tenzin's children probably wouldn't have been put into training so early if they had not been sure they were airbenders.
