Help with FB ad

Hi guys...I'm just starting with FB ads so I apologize if this might be stupid .
Strange thing here: I'm running 3 engagement ads to test some creatives. 2 images and 1 video. The images have around 40 likes each but only 1 link click.
The video did't got one single like but 6 link clicks and a lot more reach. Please help me understand which is better.
I attached ad manager print.
