Benefits of a 10 minutes + video in comparison to a video less than 10 minuets?

Is there a difference in revenue between 10 minutes + videos and videos that are less than 10 minutes? I keep hearing people bring this up and say that 10 minute videos yield much more revenue than videos that are less than 10 minutes but I haven't actually seen people back it up with proof. On top off that those videos are also favored by the algorithm (More likely to be placed on first page and get into suggested list). Is this true or are they just bluffing?
