I myself are in your position - 16 and want to fly commercially.
My advice is to get a back-up career because a job in aviation isn't guaranteed - far from.
You will also need to get finance to pay for your training. Therefore whilest working + training at the same time you will be learning to fly via the
modular route.
This involves getting a PPL and building up hours. Then you do your CPL and Instrument Rating etc....
