The Vatican is not in the Diocese of Rome. The Vatican is a separate country. It does not belong to the Italian Catholic Conference of Bishops nor is it a diocese. The pope is the bishop of Rome, but that's a separate office. The Diocese of Rome finances itself, just like any other diocese in Italy.
There are funds at the Vatican for dioceses in developing nations. They have to write proposals for these, just as you would write a proposal for a grant from any organization.
It is up to the faithful in the diocese to fund the education of their priests. In some dioceses the cost is shared between the faithful and the seminarian. As Br. David pointed out, some seminarians pay for part of their education.
Even in religious orders, until you're a novice, the order may pay for your education, but it has no canonical obligation to do so. When I entered, I had to pay for my first two years of college. Then I went to novitiate. From that point forward, the order paid for my education. Even there, the cost was shared. Many of our friars hold positions that pay salaries: parishes, schools, hospitals, counseling, etc. Every house sends a percentage of its income to the motherhouse. The rest of the money comes from begging. The faithful help us.
