Yeah. Russia never had the numbers necessary to occupy Ukraine. The whole exercise was hasty, stupid, and doomed to fail from the start. Even if they were following proper modern military doctrine, occupying a country as large, noncompliant, and capable as Ukraine has proven itself to be would be a collosal undertaking.
It's still hard not to compare it to the invasion of Afghanistan, where an advanced modernized coalition was stymied for two decades by fewer than 100k experienced insurgents armed mainly with civilian vehicles, Cold War era weapons, and improvised explosives.
Meanwhile, Ukraine's military is over 100k strong and trained by the West and armed with some of the most modern vehicles and weapon systems available, further bolstered by volunteers and foreign intelligence. And Russia's invasion force is inexperienced, undisciplined, plagued by logistical issues and poor communication, and likely economically unsustainable.
The power imbalance is so much less extreme, to the extent that Russia almost looks like the underdogs. Seriously, the only real advantage Russia has is a vast surplus of materiel, which has been rendered mostly ineffective due to dogshit logistics. They can bombard cities, but it doesn't really get them any closer to achieving their goals; if anything, it emboldens the Ukrainian resistance.
