It's a feature introduced with 11th gen. It's just your cores going into sleep mode when they're not being used.

Probably just bad reading. Somehow I can't imagine CPU being at 0 C anytime

OP meant temps, not usage.

Yes, I'm talking about temperatures too.
Uncle Webb, creator of Throttlestop, had provided this info in a thread a couple months back: https://forums.tomshardware.com/threads/why-do-my-cpu-minimum-temps-drop-to-0.3722410/
Initially introduced as a bug that Intel chose not to bother fixing, it's become a feature. 12th gen probably has it too.
When a core, or cores, go to sleep, the voltage going to them is shut off. Can't really read the sensor of a core that's shut off, so it reads as 0C.

thanks for your answer.
is it harmless or not?
