Not really, they both exist in Azure but are completely separate services/Azure resources, managed by different teams. Think of Azure as a toolbox where Azure AI and Azure Maps are separate tools. You can use them together but they are generally independent of each other.
For example, lets say you have a table of data you want to use to build a Machine Learning/AI model, and it has address information, but it's a single string and you want separate city, postal code columns, and maybe some of the postal code information is missing. You could take that address data and pass it through the Azure Maps batch geocoder service which would parse the addresses into its individual components (street address, city, postal code, state/province, country...) and fill in missing postal code information. You can then join this back up with your original dataset so it's ready for training an AI/ML model.
