China's development gives people an illusion that every developing country with big population will become big economic power. Not true. China is an exception, not a universal case for most countries. Most developing countries, including Indian, have a development ceiling. The so-called "middle income trap" can also be explained as these countries hit their development ceilings. Most countries can never reach to developed stage.
India will hit its development ceiling in recent several years. Which means, there will be no real growth for India. All economic growths in paper are just to balance international inflations.
