Fewer number of persons out of the many that holds on to this gambling strategy get to be fortunate to win a huge cash. If you're not lucky enough you can try all you can for as long as possible but may not win. In essence, you have to be extremely lucky at some point to pick that odd with high risk that would still play as predicted. I know a few folks that have done this consistently for as long as I can remember, yet they haven't made a single win from it. Which means it doesn't workout well for all.
