The delivery figure of 12 aircraft in 2022 came from a statement from Yury Slyusar last year.
I believe 12 Su-57s per year represents the production goal. Frankly, I question the wisdom of delaying production for the development of a newer variant, which may be subject to delays given the current circumstances. Having meaningful numbers of aircraft in service would allow the development of TTPs for operational use and also the integration of the aircraft into the force structure. In any case, I wouldn't surprised if the current production plans are now more difficult to realize given the likely disruption of the supply chain.
Given the figure contradicts official information and the transcription of Slyusar's words does not mention the year 2022, I would defer to Russian speakers to confirm or deny, otherwise I assume there was talk about the production goal of 1 sqd per year (fully in line with what stated above and previous known information), with the journo adding the odd info about year 2022. The line does not look ready to reach that value yet, with several complex production improvement programs in their early stages right now.
About current circumstances and their influence in the fulfilment of the Sate Armaments Program, read for yourself:

Russian defence industry places the
top priority in having their supply chains covered in case of a conflict (they never stop emphasizing this aspect), that is one of the reasons why we see the SMO now and not in 2014.
As to the integration of the Su-57 in the force, is in full swing, with very convenient real war experience being added right now, including network integration of multi aircraft grouping. It would be of course better with more units, but the current amount of airframes is already being put to use:
BTW, it is not about delaying the production but about giving time for KnAAZ and the VKS to get their work done before ramping up. As said many times, the air force is equipped with modern aircraft and there is no hurry to substitute them asap. But I would concede that for environments like the one in Ukraine, with AD present but not fully integrated, a plane like Su-57 is advantageous and it may well be that MoD decides to place more priority in its production, together with Okhotnik. I assume that LTS (especially in UCAV version) will also be decisively prioritized after the current combat experience.
I do wonder how much different the Su-57 is from the M model.
I assume from the outside quite little will change, mainly the nozzle, but probably not much more.
