AI is part of data science and ML is part of AI. So we can say that AI and ML is a part of Data Science. Where ML fails AI comes in it detect the things and train them by reading the new data. When we capture a picture in our device It recognizes what it is but as something comes which the device is not trained for their AI comes and learn themself and after sometime it start recognizing that particular thing also.
So this is AI in simple language.
So if you thing your device has AI then nope all the mobile phone have ML not AI.
