Hi Tony,
In terms of earning the certification, there are no prerequisites. If you take and pass PL-300 exam you will earn Microsoft Certified: Power BI Data Analyst Associate. As far as preparing for the exam, it may be that the author of the video is recommending those items. This is true for many of the different exams. For example, it is often recommended that people preparing for Azure Administrator certification take fundamentals first, but it isn't required that you do so.
