Just like a lot of other things from TWOP. It often seemed like if someone wrote it in their recap, it became the law there. In this case, it's being critical of someone else's religious beliefs. I guess that it's okay to be critical of the racer's beliefs, but not okay for racers to show any lack of complete appreciation for other cultures.
Proverbs 16:33 says that "The lot is cast into the lap; but its every decision is of the LORD (King James Version)." 1 Corinthians 10:31 says "Whether therefore you eat, or drink, or whatever you do, do all to the glory of God."
So, if they are Christian, then their religious text says that all things are decided by God, whether it's casting lots, a dice roll, or how fast their taxi gets them somewhere, and that glory should be given to God for every favor, including any food, drink, or not getting eliminated on a reality TV show.
