AVI is the veteran of desktop video: dependable in 1995, cranky about everything invented since. It was born in 1992, Microsoft, and its real weak spot is modern life: no proper streaming, no subtitles, no love for modern codecs.
OGG is the free spirit of audio: open, patent-free, and quietly brilliant at looping game sound. A container usually carrying Vorbis or Opus audio, both open and royalty-free. That makes it the right destination when what you need is games and open projects that want seamless loops and zero licensing strings.
