If a student finds that only unpaid internships are available in the line of work of interest, that should be a warning that entry-level jobs in that line of work will be difficult to get. If the unpaid internship experience is necessary or helpful in getting paid entry-level jobs in that line of work, that may be a signal that entering that line of work is only accessible to those who have parental financial support for the unpaid internships.
Student encountering this situation may want to re-evaluate their professional goals.
