@ foroom lluzers, I would opine that your 2639th post is one of your very finest, and so I've no doubt you're onto something.
Matter of fact, I've since realised that a wee error has indeed appeared in my above post - moreover - when I wrote this: " Lastly, it might also be argued that anyone who is thinking of chucking to towel in, only to gamble on something else instead, would be well advised to think about the true figures first."
... I did of course mean to write the syntactically correct: " Lastly, it might also be argued that anyone who is thinking of chucking <b>the</b> towel in, only to gamble on something else instead, would be well advised to think about the true figures first."
Other than that, the very best, arguably 'the horse's mouth of sources', still states that around 80% lose, and accordingly around 20% don't. HTH
