Question about themes

Dipping my toes into building a site for the first time and the whole thing hinges on a specific theme that will make things easier. When I looked into the theme on Wodpress it was labeled as exclusive to the Business WordPress plan, but I was intending on using a different host for my website so I don't need their plan.

The theme also has a free (official) download – if I were to build a wordpress site on a different host would I be able to use this theme easily, or do I have to pivot to something else? I'm sure this is a pretty basic question but I'd appreciate any feedback.
