Yeah, no. Has Russia taken a lot of fatalities? Yeah. But they're also a huge country and a lot of what they've "lost" has to some extent areas where they'd consider the population expendable.

The thing is, while NATO etc bicker about supplying Ukraine - while fighting against internal sabotage by Russia's unspoken allies - they've been actively working on a functional war-economy and production, as well as arrangements with regimes such as Iran etc.

The West has this far been in the "send some older hardware but only for defence" mode, which is just recently, slowly turning around. Committing actual troops to war is not so much, and the militaries of many members have been grossly neglected for decades. Russia continues to push the line of "you don't want nuclear war, do you?" while also actively preparing for a larger scale conflict and pushing boundaries They, and China, Iran etc have also been increasingly active in technological/cyber attacks. Eventually, I fully expect them to go for broke. This probably won't actually start at another invasion but rather as increasing/coordinated infrastructure attacks on infrastructure and technology.
