If your masters’ thesis is good enough, you could potentially edit it down to about 20 pages, and send it out to various journals to see if they want to publish. If they do, they’ll send it out to other scholars in the field who will review it/ send back edits and comments, and then you’d have to edit a number of times more. Then it might get accepted and published.

A journal article is more likely to get right into the details, with the assumption that the reader already has the most of the background information, or can look it up in the references. Many (though not all) journal articles require in depth specialized knowledge.
