I believe you don't have a license of ArcGIS Pro. To get started as an individual, you could either
1. Purchase an ArcGIS for Personal Use, which includes
ArcGIS Desktop Advanced (ArcGIS Pro and ArcMap) - 1 year subscrription
- The most popular ArcGIS Desktop extensions
- ArcGIS Desktop software updates
- GIS Professional Advanced user type
- 100 credits for data storage, premium data access, and geocoding and analysis
- A suite of ready-to-use apps for use anywhere, on any device
- Access to maps and data on thousands of topics in ArcGIS Living Atlas of the World, including foundation content from Esri
- Installation support
- Unlimited access to self-paced e-Learning on the Esri Training website
2. Sign up for a 21-day ArcGIS Pro trial.
