Hello,
Please refer to the Make.com Knowledge Base.
ACID stands for atomicity, consistency, isolation, and durability. These four properties guarantee database accuracy and stability during transactions. See this article for more information.
Make marks this functionality with a badge. Note that the ACID badge indicates the use of these properties and does not indicate whether the module is an instant or polling trigger.

Google Docs “Watch Documents” is pooling trigger, not instant. It means it must be scheduled to catch new data.

To trigger scenario instantly- you must work with AppScripts, reffer to one of many threads here like - How can i trigger a make workflow when i save changes in a Google docs? - #2 by samliew
Have a nice day!
