It is bufferingbetween parties which causes major impact to latencies. There is several ways to measure Pulseaudio latency. You cannot get rid of latency completely but sometimes default buffer sizes are too large and therefore cause worthless latency. $ …

Pulseaudio Latency Changing on Kubuntu 20.04 1 Over the past few weeks I've been having some issues with audio latency on my system. To mitigate the effects of the latency, I installed pavucontrol and changed the latency offset to -35ms to try and counter the 35ms delay that was printed by pactl list sinks | grep Latency*.

There you can set the latency offset to the value in millisecond (plus or minus). To make sure of the value you need to put start with any value e.g., 250.00 ms. Play any "audio sync test" from YouTube and set the playback speed to 0.25 (make it slower) and from there you can start noticing if the value is correct or needs to be increased or decreased.
Latency doesn't work with PulseAudio on linux - Unix ...

I guess the latency offset in your screenshot is just Pulsaudio calculating time to buffer sizes with given sample frequencies and trying to arrange this parameters with ALSA. Changing the latency offset there not showing an effect might just be an ALSA driver not supporting much variety in buffer sizes.
