Is the canon rf 24mm f 1 8 macro is stm good in low light?

Yes, it's a good low-light lens, mainly because f/1.8 is a fast aperture. It gathers far more light than a typical kit zoom, and it's stabilised, which helps you hand-hold in dim rooms. That's the case I make for fast primes in Lenses.

On full frame it frames as a true 24mm. My sensor guide says full frame is worth it for low light, so I'd pair the Canon RF 24mm f/1.8 Macro IS STM with a full frame body. Good choices from its list are the Canon EOS R6 Mark II, the Canon EOS R5 Mark II, or the Canon EOS R6 Mark III.
