India has a democracy, so Yash says every country in the world must also have a democracy, since…

Why

Yash's starting fact is right — India genuinely is a democracy, and it's true that many countries around the world are too. Where the step breaks is assuming that because his own country's system is common, it must be universal. Countries around the world today are governed in several genuinely different ways: some are democracies where citizens vote for their leaders, some still have monarchies (with a king or queen, sometimes alongside an elected government, sometimes not), and some are run by a single party or leader without the kind of open elections India has. Each country's system grew out of its own particular history, and there is no rule that every country must land on the same one. Test: pick any three countries at random from a world map and look up how each is actually governed — it is genuinely not the same answer every time. No, different countries have different systems: democracy is widespread, but 'common' is not the same as 'universal', and several different kinds of government exist side by side in the world today.
