I ran someone down by accident it was my first driving offense, will I lose licence?

I pulled up behind a parked car, at a zebra crossing, the car was particially parked on the crossing waited approx 2 mins, nothing happened so I went to overtake and a young boy got out of the passenger side of the parked car and ran across zebra crossing into side of my car. I'm being done for dangerous driving, will I lose my licence? It's my first offence.
