A trader is a market capitalist who studies the direction of assets with the aim of taking profit based on changes in the price of the asset or assets. A trader is a reader and a studies. Anything outside reading and studying (research) is plain gambling. Fundamental traders deal on news and technical traders deal on tools made available to spot market trends , peaks, direction and state.
Seriously the traders mindset is kind of different from what you're saying tho you might be abit on point cause a situation whereby a trader doesn't read or study but have a good positive outcome in his trades what do you specify that person as? But what I think is a trader needs all it takes to be successful but most importantly he should know when to take huge risks and make necessary decisions because there usually be a change in the market predictions and your decisions matters at this point, and again having the right information matters alot too.
