Here's the original video
https://www.youtube.com/watch?v=oRValgHDvxEI don't know why they create such video about gambling addiction, but in their description, they wrote like they're also speculating whenever Germany won or not.
Germany was second strongest team in 2014, so the chance to win is high, if they want to make sure they will lose, they should predict the unknown country who never won World Cup, Singapore for the example lol.
