For sure parents play a big role. The "forced practice" and colaboration with the teachers certainly are factors. I think a socio economic context also plays an important role.

In an affluent family (as define by people who didn't have to worry about money for three generations) access to education is a given, and therefore less valued.

If your family is poor and your access to education is more uncertain, you'd value what you get to learn a lot more. In this context learning and persevering takes on a dimension of "duty" to help out the family. This feeling of duty towards your family caused by family poverty can transfer for several generations. If you grow up aware of the the struggle that your parents and grandparents had to go through to get to where you are now, you end up feeling obliged to learn this math thing.
