You bet your ass its a win. On the street the only thing that matters is who crosses the finish line first. The second both cars are in motion it's a race. If one racer leaves before the signal and the other doesn't move it's a no race and either they line up again or if prediscussed the early leaver loses. There are no rules in a street race. Hopefully an honest non biased person is holding the $. I've seen plenty of races where scum bags did some crazy chit and still lost and wouldnt pay.
