Hi Sameer_J,
welcome to the Apple (user-to-user) Community.
Re: AirPods Pro (1st Gen): "every time I am on a phone call with these, people on the other side are never able to hear my voice"
Am no expert in this area, yet your question surely deserves a response.
Apple support have articles online that may help trouble-shoot :
Eg: You may need to update your iPhone's iOS version to the latest.
About iOS 16 Updates - Apple Support (says iOS 16.4.1)
That way the firmware on the AirPods will automatically update also, when paired: About firmware updates for AirPods - Apple Support

Re: "people on the other side are never able to hear my voice and only hear the background noise".
You might want to restart the device you are using for phone calls ..
Eg: How to: Restart your iPhone
You might want to check you have not accidentally turned on "Silent" mode or "mute",
and
try experimenting with the volume during a call.
Eg: How to put your iPhone on vibrate, ring, or silent mode - Apple Support
or
While on a call on iPhone – Apple Support
says:
"Adjust the audio during a call
To change the volume, press the volume buttons on the side of iPhone.
Or
swipe down on the call banner, ....... then
Mute: Tap the mute button."
