You do know the Probes are in the thousands at a low base right? Also, you also know every time a probe is destroyed, the energy after blowing up goes back to the ship where the energy is once put back another shell right?
How? The Probes don’t tire, nor sleep, nor feel fatigues. The probes feels nothing, and they are in the thousands or even more. How is this a stalemate?
^ 'All-out' Superman and Doomsday were shredding through them. WBH should be able to as well.
Thing is, if a Probe is destroyed, it's essence is sent back to the Mothership, and a new Probe is created to replace it. So short of completely nullifying a Probe's energies(which neither Hulk or Thanos can do), they'll just continue coming back, endlessly. Think that's what DS was getting at.

No one is saying is that. The Probes even of destroyed, the energy is returned back to ship for a new one to be reborn, so as long as Prime and his ship are alive, they can’t win.
So at the end of an hour, the probes which have all been smashed would be back on the battlefield. WBH would be the same as at the start. Thanos will tire and will eventually fall, but not Hulk.
