When Ukraine had plenty of artillery ammo where did Russia dig in and was able to stay for a long time? They didn't. They got steadily pushed back or they were slaughtered. It takes a long time to "dig in" deep enough to protect from modern artillery and that is rarely able to be done when armies are in contact.
If you notice the timelines, Russia only made gains when Ukraine was running low on artillery rounds and rockets. Three years ago, when Ukraine didn't have much in the way of modern precision artillery or rockets, the Russians were 300 miles west into Ukraine. As Ukraine gained more modern artillery, rockets, and drones, they were able to drive the Russians back even though the Russians had much more troops and armored vehicles.
It's not a matter of how many boots or tanks you have on the ground - it's a matter of how many artillery rounds you can send to prevent anything staying alive on that ground, or even under it. And you don't have to be hit with artillery, just being near the impact concussion pressure can knock troops and equipment out of action.
There are very good reasons that artillery has long been called "the King of the battlefield". And modern artillery has only gotten better at earning that title.
