Classical ML is still the dominant form of ML, and is preferred for most forms of tabular data (think spreadsheets). It's just far faster and often more effective than deep learning. Deep learning's greatest strength is that it can do the feature generation for you, which is great for more abstract data inputs such as pixel arrays and word sequences. Deep learning receives a lot more attention because it's doing things that normally would require a human to do.
