Satanist/Psychic told my boyfriend M21 he will die at 30

So when me F19 and my boyfriend M21 got together a few months into our relationship he told me that a satanist/psychic told him he was going to die at 30. He said that they used to FaceTime when he was 19 and talk and he told her his name birthday age and where he is from and she didn’t do a actual reading they were just talking and he asked if she could see when he would die and she was like yes and he was like when and she was like “you’re going to die at 30 years old” he said she seemed legit and that one time she told him to try something where he sat and just feel and try to feel his energy and he felt like a burning feeling but that was it he never gave her anything else and he ended up stopping talking to her but I’m so scared because all I think about is that what if he dies at 30 I guess my question is how likely is it that she is correct? He also is learning more about god and is starting to believe in god more and more now idk if that changes anything just thought I’d add that in. Please help
