I am 18 years old with zero digital skills. Is it still realistically possible for me to start freelancing today and make money within 30 days?

It is possible but you really need to work harder. You have met with the first criteria which is meeting the legal age. This means by the law, you can be making money as you want online. But getting money on freelancing within the thirty days time frame may be somehow difficult. That's why it is better if you are determined. You need to make sure that you have the skills and be consistent with it.
