Sorry, my fault, I misread. The same applies to appsink though :-)

You will get buffers as they flow through the pipeline in the chunking
used there. So after udpsrc that would be udp packets as received, after
an RTP depayloader that might be udp payloads (possibly whole frames,
e.g. if you force the depayloader to output H.264 AVC instead of
byte-stream NALs).
