It is certainly true, if a woman can be an airplane pilot, a woman can be a sergeant, and a woman can be an engineer, why can't a woman gamble? In ancient times there may have been an idea that only boys will do the work and boys will always have priority but now society has changed and now women have equal rights. A woman can be a good gambler just as a man can now work outside as a woman can now work outside just as a man can gamble. If that girl has the confidence that she can do something good by gambling then she can definitely gamble as a girl.
