When you first look at soccerscanner it seems like a lot of numbers and coloured blocks but once you realise what its showing its very easy to understand.
There is a video I recorded to cover the basics on youtube https://youtu.be/YOuDN3HJJ7g
Basically SoccerScanner is showing you the details for a large number of games on one screen, this array of numbers can look complex so i've added colour coding to better show opportunities. Whenever a statistic is highlighted (as Corners are below) that means that particualr statistic is double or more than double the opposition. By using this it gives you a visual representation of which team is on top
