What is the difference between RX and DX cameras?

Nikon refers to their cropped sensor (APS-C) cameras and lenses as DX and their full frame cameras and lenses as FX. FX and DX lenses came used on either camera type.

RX cameras are made by Sony and just seem to be a model designation for some of their compact digital cameras like the full frame RX1R and 1 inch sensor, RX100 III. All the lenses on these cameras are fixed, unlike the Nikon DX and FX cameras which use interchangeable lenses

Here is a link that compares the sensor sizes of the Nikon D3200 (DX), Nikon D4 (FX) and Nikon "1" sensor (None of the Sony RX cameras are listed on this site but the sensor sizes are identical) Nikon uses DX to refer to bodies with 23.5 x 15.6 mm sensor or lenses optimized for that sensor size.

Sony uses RX for some camera models with 13.2 x 8.8 mm ("1 inch") sensors and built in lenses. RX cameras are designed specifically for medical use.
