The flybys provide course changes for very little fuel, including pretty significant velocity boosts. It's not uncommon for a probe to spend a while ping-ponging around the inner system just to get enough speed to reach the outer planets. I doubt the probe has a whole lot of delta-v left once it leaves Earth the first time, probably just enough for course corrections so it can hit the flybys precisely.
