the sharper you are, you can see more opportunities from the market. I know a guy who can identify most of intraday trends with 95% accuracy. there is James simons too who is consistently profitable. I am also coding a system which can capture most part of intraday waves with at least 75% accuracy.
let me give you an example, a picture of dog, if represented in digit form, is just 0110101100110011111010. it is random to naked eye, but it shows a dog on webpage. so you think a picture of dog is random or not?
Even the random number generated by computer is not random at all. randomness is only meant to the untrained eye. you need inspiration to see through the randomness. it is true not everyone has the capability, and for some people, no matter how intelligent and how much effort invested, they can not see the true picture.
