The induction problem

Happy Holidays!
1-Does the problem of induction according to Yom only claim that we do not know what the cause was that caused the phenomenon before our eyes, or does it also claim that there is no causality at all? I understood that we only do not necessarily know the correct cause, but it is clear that there is deterministic causality, is that true?
2-Assuming that it is, then is there anyone who claims that there is no causality at all?
3- I don’t really understand Yom’s problem, and even if we don’t know the absolute cause, would it still be enough for us to rely on it for how we will act in practice (since seemingly the whole purpose of science is to enable us to act in reality, and what does it matter if it is not the real truth)?
Thank you very much!
