Confusing Power BI Licenses

I was reading how can I interact with Power BI as Free user https://learn.microsoft.com/en-us/power-bi/consumer/end-user-features

As a Power BI service user with a free license, you explore content (such as reports, apps, scorecards, dashboards, and more) in order to make business decisions. That content is created by designers who have Power BI Pro or Premium Per User (PPU) licenses. In order to share it with users with free licenses, designers need to publish that content to a group workspace backed by a Premium capacity.

The above quote "workspace backed by a Premium capacity" is too confusing for me. We have only PRO licenses.

Do we need to pay 6,858 dollar per month in order for a workspace backed by Premium capacity?
