Yes. However, an ArcGIS organization (ArcGIS Online or ArcGIS Enterprise) account is still required to access web maps and services and to share content created in ArcGIS Pro to the web. Even with an ArcGIS Pro Concurrent Use or Single Use license, you maintain an account in your ArcGIS organization and can sign in to it from ArcGIS Pro with your account credentials. With a Concurrent Use or Single Use license, it is not necessary to sign in to ArcGIS Pro to use the application; only to use it in ways that interact with ArcGIS Online. See Sign in to your organization for more information.
