Quantity is a quality of its own. I’d say Ukraine is hanging on with advanced weaponry. It needs the mass to push Russian troop advances and repel their forces out of their country.
Anything else is keeping the status quo of roughly even wins and losses, which will never lead to victory in the next decade.
Russia claimed and held territory. Their military leadership doesn’t particularly value human lives in this conflict and hasn’t historically either. I have no doubt that they will continue the course suffering heavy human losses and eventually find some form of victory.
Ukraine needs more people if they want any hope of staving that eventuality off. The Russians have very different ideas of fighting a war of attrition.
