Several reports from the Ukraine offensive stated that Ukrainian forces captured so many Russians, they were running out of places to hold them.Routs agreed, the hundreds of intact AFVs captured supports this. But the lack of tens of thousands of Russian POWs suggests the AFU has been unable to fully exploit these routs, allowing the Russians to essentially walk away to fight again another day.
That sounds like a significant number to me.
