Google has numerous internal applications other than websearch that use machine learning, such as spam classification (Gmail), image segmentation and recognition (photos, image search), text-to-speech and speech-to-text (assistant), very small generative tasks (smart reply, smart compose), predicting which videos will be watched (YouTube), and even operating the pumps and fans in their data centers.
