Machine Learning is more than just neural networks. It involves various classification and regression algorithms like KNN, SVG, etc... It recently (since 10 years more or less) became more popular due to the success of neural networks and deep learning (deep neural networks) in a variety of tasks such as speech recognition, object detection (in images) etc... A neural network is just a function, or a mapping if you prefer, of some input to some output (not much different from a basic function y 2*x 5, just much more articulated). For example, Deep Neural Networks (Neural networks with many layers) can, given an image, tell you if a particular object you are interested in is present (in which case outputs 1) or not (0).
