If you push a 500 MB file to Git LFS, you'll use 500 MB of your allotted storage and none of your bandwidth. If you make a 1 byte change and push the file again, you'll use another 500 MB of storage and no bandwidth, bringing your total usage for these two pushes to 1 GB of storage and zero bandwidth.
If you download a 500 MB file that's tracked with LFS, you'll use 500 MB of the repository owner's allotted bandwidth. If a collaborator pushes a change to the file and you pull the new version to your local repository, you'll use another 500 MB of bandwidth, bringing the total usage for these two downloads to 1 GB of bandwidth.
