Does having a high risk mean I will develop the hereditary condition or present a complex personal trait?

No, because hereditary conditions and complex traits are regulated by genetic and environmental factors.

Genetic risk measures the impact of the genetic factor on the development of a hereditary condition; however, environmental factors ultimately have a strong impact on the development of the condition or on presenting a trait.

A clear example is the relationship between lung cancer and tobacco use. In this case, a person with a high genetic predisposition to a disease as lung cancer, but with a healthy lifestyle, may not develop the disease. On the other hand, a person with a low genetic predisposition, but who is a smoker and has unhealthy habits, may develop it.
