While the famines were real, and a result of British rule, that wasn't because India was part of a "world capitalist system". Capitalism doesn't just mean "people doing things for profit" but rather the use of capital to build up industry, which Britain had no intention of doing in India.
Capitalism is a system where one class of people (workers) sell their labor for the profit of another class (owners/capitalists). So feudalism was neither capitalist nor industrialist. Colonial capitalism - not typically industrial but still capitalist. Industrial capitalism - both industrialist and capitalist. The modern American economy - service based not industry based - but still capitalist.
