There's really a very slim chance to find a scholarship for flight training, except probably in the military. There's already a surplus of pilots in some parts of the world. And pilot as a career is no longer lucrative.
As I mentioned before, flight training can be done anywhere. Accumulate enough flight hours and you can qualify for CPL. Specialized trainings for modern passenger planes are usually done at training facilities of manufacturers such as Airbus or Boeing. And pilots are sent there by their respective airline companies.
