Well if God created everything then because of God everything exists so everything does need God. I think things do happen on there own but only because God gives them the power to, we are the only species on earth that has the ability to reason and make complex decisions and I believe that God gave us that gift.
Drawing a royal flush and the ability to teleport are completely different things. If it is true when you say one person a month can draw a royal flush at a casino then that would mean over thousands of people have done it already, and I don’t think that I recall anyone having the ability to teleport from one room to another or be at the same place at the same time. There was however an incident in the Bible that after Jesus had been crucified and laid to rest in his tomb he rose from the dead and appeared to all the disciples and then 500 other people, this is by far an even greater feat than teleporting from room to room.
