How does remote control works in modulating and demodulating signals and why does it works in 38khz frequency?

Your question is flawed.
Remote controls work in so many different frequencies.
kHz, MHz, GHz, THz. Etc.

Am sorry Martin but I was concern with TSOP that works in 38 khz frequency.

since your Op didnt state if this was a radio remote for say a drone etc or an optical remote for a TV etc
it was difficult for people to give you a decent reply without further info

Isn't 38kHz the 'baud rate' at which the data is sent rather than the carrier frequency?
