Ukraine being able to capture so much Russian land will eventually affect the entire conflict. And Russia has pulled some troops from Ukraine to go try and get it back, but they are not having much success yet.
Ukraine attacking arms depots deep in Russia will affect the conflict too.
When we attacked Iraq in the Gulf war, they had the absolute best weapons Russia had made. We had no problem destroying Iraq's military then. They had the best MIGs and the best Tanks they had bought from Russia.
Today, I do not think Russia's weapons are all that much better. If they are, why is Ukraine still in it. Using all the modern weapons Ukraine has been getting, they may actually start driving Russia back out. Russia just had time to build such tough defenses, it is not going to happen quick. And apparently, Russia does not care about losing so many troops. They just keep sending untrained boys into battle.
