The tracks are usually re-encoded, which costs a little quality. If the 3GP already carries codecs MP4 accepts, they are copied as they are and nothing is lost.

What changes
Only if your 3GP already has H.264 or MPEG-4 video with AAC audio does MP4 accept it as it is, so the converter copies the tracks without re-encoding, in seconds and with no loss. If not, or if you change the quality, size, scale or trim, the video is decoded and compressed again, and loses a little more detail.
If it’s copied, it’s about the same size as the 3GP: only the container changes. If it’s re-encoded, it gets larger: MP4 needs more space for the same content.
When it’s worth it
Choose MP4 for: Phones, websites, social networks, and TV. Small files for the quality, usually with H.264 or H.265 inside.
Stay with 3GP for: Videos from old mobile phones.

Questions
Does converting 3GP to MP4 lose quality?
Usually a little, because the video is compressed again. Only files that already carry a codec MP4 accepts are copied without loss.
What is the MP4 format?
A container that holds a video track, one or more audio tracks and metadata, and nothing else: which codec sits inside is a separate question. H.264 or H.265 video with AAC audio is the combination almost everyone means by MP4.
What is the 3GP format?
The 3GPP container for video on mobile phones, which is what camera phones record by default. It belongs to the MP4 family and holds H.264 video with AAC audio, sized to keep the files small on a phone.
