Both are getting changes down from a remote repo
If you plan on collaborating, these are critical

git `fetch`

git fetch origin

Downloads commits, files, and refs (branches, tags) from a remote repository to your local repo.
Updates your remote tracking branches (like origin/main), but does NOT change your current working branch or working files.
Allows you to see what’s new on the remote without merging or modifying your current branch
After fetching
- you can check the changes (e.g., git log origin/main) before deciding what to do next

git `pull`

git pull origin main

Combines git fetch + git merge (by default).
Downloads changes from remote and immediately merges them into your current branch.
Updates your files directly, so your current branch reflects the latest remote commits after the pull.
