You are right, trading is not a dangerous activity, but it is a risky activity. The main risk is losing money, but the reward is gaining profit from it.
There's no business that doesn't have its own level or type of risk. None. The only reason people get severely frustrated with their loss in trading is because they erroneously believe that trading is a shortcut to riches. Someone wants to become rich from trading after a week of practice and thinks it's okay if they've that conception and shouldn't be disciplined? Nah. It doesn't work that way. We've to pay the dues and then expect our rewards in the harvest season. Those who've put in the works over the years in trading will tell you it's not even as risky as we make it out to be. All it needs is patience and learning.
