What is the difference between Google Ads and Google business listing?

Google Business allows you to create and verify your local business on Google, so that your business information can be shown in Google Maps. With Google My Business, you can also add business information that can appear on Google.com, Google Maps and Google Earth when someone searches for your business name or category. There are no charges for clicks with this Google service, and results are more locally based.

AdWords (Google Ads) is an advertising service by Google for businesses wanting to display ads on Google and its advertising network. The AdWords program enables businesses to set a budget for advertising and only pay when people click the ads. The ad service is largely focused on keywords.
