Yes there are successful people who are agreeable and conscientious. There are also people who have low IQ and are successful. However, these personality traits can be measured as predictors of success. Conscientiousness is usually considered the best predictor of success, followed closely by intelligence. However, agreeableness is considered a negative predictor of success. Meaning the more agreeable someone is the less likely they are to be successful with everything else held constant.
So you are right, no "template" exists, but studies aren't looking for a template. They are looking at predicting something and agreeableness negatively correlates with success.
It's like tall people, on average, make more money than shorter people. Sure, I've met multi-millionaires who are under 5'5", but height is a predictor of earnings when you look at populations.
