The facts are that those Russian warships were sunk, regardless of who reports it.
They are losing one about every other week so far this year - the same way.
Those ships cost $60 - $80 million a piece, and take years to produce. They have specialized functions (like the landing ships, and the Kalibr cruise missile launch capability) that are in short supply to Russia, and cannot be replaced through the Bosporus Straits for the duration of the war.

The Sergey Kotov was one of six patrol boats belonging to Project 22160. Two remain to be completed and activated. All construction was at Zelenodolsk, on the Volga River. From there they can access the Black Sea without using the Bopsphorus Straits.
The Sergey Kotov was the last Project 22160 vessel commissioned on July 30, 2022. The remaining two, the Viktor Veliky and Nikolay Sipyagin were scheduled for a 2023 commissioning. Construction should be nearly complete.
