So I recently got jio fibre and previously I was using BSNL ftth and its input power is -13.0 and BSNL ftth works greatly up to -22 so its great, but the lineman who installed jio cable said that the input power for my jio ftth is -22 and jio ftth operates up to -23 so will it be a problem ?
Or it is completely OK.
BTW the lineman told me that there will be no problem

Most ONTs have optical power sensitivity till around around -28 dBm, so you should be good. This is basically the lowest power level at which the ONT can reliably function.

My BSNL FTTH power level is around -25 dBm and works just fine.

However a lower value would mean that as the provider adds more splitters this would further drop. Hopefully they keep track of the levels and make appropriate changes when required.
