In most of the cases, the changes made online by other collaborates will replace or succeed your offline changes, if any. Only when you connect your device to the internet, your offline edits will sync. When it comes to shared files, the collaborators will not view any edits immediately. Note: Google files such as Docs, Slides, and Sheets do not count in Google storage, but if you make them available offline, they will take up storage on your device (mobile or PC). The new version will then be synced to your device and made available offline as well. Later, when you gain access to the internet, Google will check for changes in the file and update its online version accordingly. That said, any changes made to the file will be saved locally. Once a file is available for offline use, you can open and edit it without an internet connection.

Note: Offline files work only on Google Chrome browser (Computer) and Google Drive, Docs, Sheets, and Slides mobile apps (Android and iOS). To make it easier for people to work anytime with these files, they can be accessed offline – without Wi-Fi or mobile data. Normally, Google Drive and its components such as Google Docs, Sheets, and Slides need the internet connectivity to open and perform actions such as editing, saving, etc. What Is Meant By Offline Files in Google Drive
