How do I start?

Hi all a quick about

USA Based , Bachelors Degree in Business Management

Been in sales ( Retail , SMB , B2B )

I want to change careers and came across digital marketing. I want to learn more but haven’t found a clear path.

I have seen some info like courses ( Coursera Udemy Etc)

My question is , is this the starting point or am I missing something?
