Is my account cursed?

So, I have been playing(F2P) genshin for around 6 month, since the last furina banner. Since then, I've wished on 2 limited character banners and both time I lost my 50-50 and that too on hard pity every time. I've looked at my wishing history today and it looks like this :-

Qiqi - 75 pity Kazuha - 78 pity Jean - 79 pity Neuvilette - 79 pity

So, I was wondering if my luck is just bad or some accounts are just cursed. Will this ever gonna change? I don't mind losing my 50-50s, but at hard pity everytime?
