Is MBA worth it for my profile?

Hello, I want to know your opinion about the usefulness of an MBA for a case like mine. I have worked many years, but just in jobs like food delivery and uber driver, autonomous low qualified work, nothing else. I started studying at 28, and I'm graduating now at 32 from political science but have no job experience in any management position or even a normal entry job in any company.

Is an MBA (I have a high chance to do it for free in Korea and receive a stipend due to my high GPA, already talked with some admission officers, so take this into account too) worth it to improve my employability and stop having menial jobs? Do you know of any case like mine that was successful?

Thank you in advance to everyone!
