The Chrome Extension gives a tonne of great information when you are product researching. Sometimes you may find a keyword with high revenue but low search volume.
For example currently “purple yoga mat non-slip” has less than 50 searches per month but the average product on that page generates around $48,000 per month.
Av Revenue - The average estimated monthly revenue of the listings on page 1 across ALL of their keywords.
Search Volume - Estimated number of exact match monthly searches for this exact keyword phrase on Amazon.
In short the search volume is directly attributed to the keyword phrase that you have searched and the Average Revenue is attributed to the total revenue across all of that listings keywords.
