A company recruits many interns for one position, does it mean that this company is not good at retaining people?

Friend, you think too much. ..........................

1. If your friend really hurts you for profit, it is not a real friend, and such a friend is ok without it.

There should be a reason for the company to recruit people. Don't you know the quality of this company by feeling? Suppose you work in this company for a month without paying you, you lose a month's time, and this company loses time, money and reputation. In short, it will be much more than you pay. Assuming that this company pays you normally, even if you are later dismissed, you can still get paid and learn what you want to learn.

Summary: Everything is unpredictable. You should analyze your future by yourself. You will graduate soon, so you need to be independent. Good luck!
