<p>I bought a video and see a lot of meta data. What do these metadata mean (overview summary)? Is there something like watermarking to track who the owner is?</p>

They are not tracking buyers - those are metadata written by the authoring program (Adobe Premiere Pro CC 2015).

All those `Ingredients*` and `Pantry*` tags are XMP tags which are really easy to remove.  Either remux the file with ffmpeg or with [exiftool](https://exiftool.org) you would run `exiftool -XMP:all= video.mp4`

I see no need to worry about those meta data or why you should remove them.

Pantry and Ingredients tags refer to asset tracking. In fact most of this data are production related and not relevant in any way for a consumer. The rest tells you about technical features, like the resolution or video codec.

A watermark is something different. If you want to protect digital data you typically use DRM or could hide it steganographically in the video content or even make it plainly visible. Metadata can be removed too easily and are not used for this purpose.
