Except that it's not 50/50, at least in the case of humans. With humans, it's about 1.07/1, in favor of males.
The mechanism is much more complicated than a 50/50 chance of inheriting some chromosome.
A lot of mammal species eliminate excess males using other methods - mainly bloody fights to the death, which also tends to result in the remaining males being the strongest ones.
