SurajM Yes it definitely is contradictory. But read it in its context, what the OP asked :
It is a well known experiment in probability. And I was giving an answer to his observations. His Q basically revolves around probability !
Now back to this thread. How does this 50:50 probability become 60:40 or 70:30 ?
From a bag containing 50 red and 50 green balls, what is the probability that you will end up with a green ball in first attempt ? = 0.5 !!!
Now while preparing this bag of balls, add more green balls (70) and less red (30) and repeat the experiment. THE PROBABLITY OF YOU SUCCEEDING IS HIGHER NOW.
Now I hope you are not finding them contradicting. And also I hope its has convinced you that trading is not gambling. If still you consider it that way then I would say even a chicken laying eggs does gambling and lays multiple eggs for higher success rate. Nature follows this principle. Even a kirana shop owner stocks his shop with multiple products. We are no different.
