I suppose it takes a lot of deltaV to get a stable orbit over the sun poles?

You'd need to completely cancel out the rotation of the solar system, far beyond what we have the technology to do.
It does, but most of the needed dV is harvested from the planets during gravity assists. The probe is accelerated/turned several hundred or thousand m/s and in exchange the planets it passes are shifted/slowed/turned by maybe 0.00000000000000000000001 m/s. In this case, the probe largely needs to slow down, to bleed of the speed it got from being at earth's orbit, so the planets are probably being accelerated.
It's doable with gravity assists. Ulysses got up to 79° inclination using a Jupiter flyby.
