Shopify guide suggests you can be profitable, generally after working 10-15 hours per week, for 12 months. How much of the hours can be from learning?

Quoting the passage below. I'm finding myself spending a lot of time on learning copywriting, digital marketing, SEO, web design / graphic design, etc. I know the passage says that "it's possible", but assuming it's a reasonable expectation, would you think it's fine to assume that a large portion of that 10-15 hours per week, in the first few months, will be going towards researching / learning?

"All businesses and entrepreneurs are unique, but it’s possible to generate a $1,000–$2,000 monthly income stream within 12 months working approximately 10 to 15 hours per week building your business."
