Does Coinbase support both Coinbase & Coinbase pro?

Excuse me, I have a question regarding Coinbase's platform offerings. I was wondering if Coinbase supports both its standard platform, Coinbase, as well as the more advanced version, Coinbase Pro? I'm interested in understanding the differences between the two and whether users can seamlessly switch between them within the same account or if separate accounts are required. Could you please clarify this for me?
