Q:

Is BigQuery GitHub contains all the data?

Documentation says that GitHub data collection contains all the code from a GitHub

This 3TB+ dataset comprises the largest released source of GitHub activity to date. It contains a full snapshot of the content of more than 2.8 million open source GitHub repositories including more than 145 million unique commits, over 2 billion different file paths, and the contents of the latest revision for 163 million files, all of which are searchable with regular expressions.

But I can't find my code in it:
SELECT *
FROM [bigquery-public-data:github_repos.files] 
WHERE repo_name LIKE 'Everettss/%'; 

results with: Query returned zero records.
Here is example of one of my repo: https://github.com/Everettss/isomorphic-pwa

EDIT
After Felipe Hoffa answer, I've added LICENCE to my repo, so my example may not be valid.

A:

The linked sample project is not part of the BigQuery dataset, because the linked project is not open source.
What do I mean with this: For a project to be open source, at a minimum it needs to have a LICENSE file, and GitHub needs to be able to recognize that license as one of the already approved open source licenses.
