The file is decoded, resampled to the rate you choose, and re-encoded as MP3. Because MP3 is lossy, the re-encode costs a little quality, so resample when a system genuinely requires a specific rate rather than as routine maintenance.
Video editors want 48 kHz to keep sync math clean. Telephony and IVR platforms expect 8 or 16 kHz sources. Some older hardware and software simply rejects rates it does not recognize. One resample here usually unblocks the pipeline.
