Okay, little buddy, imagine you have a super smart friend, let's call her "Sally the Super Smart Robot". Sally can play video games really well, but only after she's watched a billion hours of YouTube videos of humans playing the same game.
Now, let's say Sally wants to learn how to play, say, "Tetris"! But Sally's not just going to play it for a second, she's going to learn from every single block she's ever seen. She's going to remember where every single block goes, and she's going to be so good at it, she'll be able to make a Tetris board in her sleep!
And that, little buddy, is Deep Learning! It's like super smart Sally learning from all the data in the world, so she can do cool things like play games, recognize pictures, and even talk like a human!
