Do you agree that poker gives a gambler the greatest possible control over the outcome?
Em. It does if you compare it will all the other forms of Gambling which are all based completely on luck whereas Poker does have a
slight skill advantage and also with some hands you know the outcome already, for example, you make a Royal Flush and after that you can bet an Elephant because no matter what, you know you can't lose.
In the spectrum of controlling your own destiny, isn't the correct ranking:
Poker > Sports Betting > Blackjack > Dice > Lotteries
How do other people rank them?
I'd rank the same but after sports betting, I'd put all of them in the same category:
Edit: I think Horse Racing should make a place between Sports Betting and all the Casino based games? Based on a Horse/Jockey's history, experts can still predict the outcome
to a certain extent, same as Sports betting.
Poker > Sports Betting >
Horse Racing > Casino Games.
