No, theres more complexity to the story. Do some research on what caused famine in India and how there's more questions around Churchill and WW2 influences.
Start with https://edition.cnn.com/2019/03/29/asia/churchill-bengal-fam... (Churchill’s policies to blame for millions of Indian famine deaths, study says) , which IIRC references https://agupubs.onlinelibrary.wiley.com/doi/abs/10.1029/2018... (Drought and Famine in India, 1870–2016)
