The birth rate for males is higher. For 2020, the ratio varied between around 1.02 males/female to 1.13 males/female, depending on which country you're looking at. Since those children then go on to have higher likelihood to die before maturity than the females, the two groups are pretty close to 1 male/female at maturity.

That is the thing that the Fisher principle predicts - an environment where males die without reproducing more frequently than females do will produce a selective pressure that means more males will be born in order to compensate.
