They absolutely are not. There is no such thing by default, only if all your devices are from a single platform authority (Apple, Google, or Microsoft) and you trust them. Most people do not fit it that category.
Even on Apple's walled garden ecosystem it's hard af to get this magical transfer to new device to work.
