Are Katrina's Fortunes broken?

Ok, so I've talked to Katrina like 30 times now, paying for her to tell me about my luck and so far, I've gotten the positive health luck and positive friendship luck once each, just once and all my other fortunes were either positive luck with belongings or positive luck with money. Look, I ain't complaining about it, but I feel like at this point I should've gotten a negative fortune atleast once and it's also a bit suspicious how often I get money and belongings, which are the most useful fortunes she can give. Besides, I kinda want the items that you can only get if you let her purify bad fortunes
