My take is instead of T-72, western vehicles mean even if they are given tomorrow they will not be available on the battlefield until April-May given the training required.
AFAIK Russians have been piling up all those T-90M, T-72 of various flavors, down to T-64M. During the last few month where Surovikin has been on total defense on the ground and letting loose with flying mopeds and cruise missiles as he's a VKS man the ground forces have been rebuilding strength consistently, with tank force perhaps recovering 70-80% of the numerical strength they lost over 2022 (but not same quality obviously).
Now they put Gerasimov in charge which suggests pure defensive phase is over and Russian are about to return to offensive operation. Perhaps not quite the intensity of start of the war in 2022, but certainly more aggressive than the Surovikin period.
During the defensive stages, they've been heavily using old T72 and even the T62 from storages. The heavyweights on Russia side were the T80BV, which are evolutionary dead ends as they're not further upgraded anymore.
Number of confirmed lost T90M are very low, not even 2 digit numbers.
Russia is supposed to have hundreds of T90M as well as a little less than a hundred T14.
There is also the "new" T72M1 variant which looks like a rapid conversion rush job.
If a new offensive is coming, it is likely that they will use T90M and T72M1. The idea would be that after grinding down the AFU to the point there is not much armor or heavy weapons left, they will just commit their best armor and go all in.
It is perhaps also due to this danger which cause the discussion of arming Ukraine with the only tanks that exist in number among NATO have come up increasingly often. An infusion of several hundred tanks will dash Russian hopes of brute forcing a massive breakthrough and put them back into the grinding stage of the war.
