On one hand you have all the information it extracts from non text sources: books, images, audio, video, non English languages, etc. They use machine learning from them. On the other her hand they also use ML in the search engine to understand better your query (that is why it shows results that sometime doesn't have the keywords you typed), to rank the results based on what you would like more, etc So the question is where Google doesn't use ML. If there is data there is a way to apply ML and create value.
