While you're correct about that... IIRC, Ukraine actually has plenty of tanks. Albeit Soviet-tanks like T-72... but that's still a proper tank.
Its the IFV department where Ukraine was severely lacking in... and where we can get the best improvement to Ukrainian strength per ton-of-weapons shipped over.
Well, their tanks are shite compared to Western tanks. They've also captured a lot of the various BMPs, but again those are shite. As of Oct 2022, Ukraine has captured roughly 500 IFVs. I don't have the patience to go through all of Oryx's data to see how many they've lost to the Russians, but they seem to have a decent number.
I think that the Bradley will be a big help in comparison to the performance of a BMP-3, but the delta between a Challenger or Leopard (especially Leo 2A46) to any T series tank is huge.
