O2 sensors go in the exhaust, generally.

Your RZR don't have oxygen sensor, what you see is a map sensor.

I think technically it is a tbap sensor. Temp and barometric pressure.

For about $200, maybe less, you can add a wideband O2 sensor to the exhaust and put a gauge in the dash.

All of the above. The reason you would want to have a oxygen sensor is to feed information to a air fuel gauge you would install in the dash. The reason for the gauge is to give you information on how rich or lean your engine is running. If you are stock don't bother. If you have done a intake or exhaust it will tell you it will tell you it's running rich. Then you go buy a fuel controller and load in a map (instructions for the controller) then you can use the air fuel gauge to see if you got the right map. Is that clear as mud
