Is the 50/50 even real

I started playing last year around last week of 4.7 and managed to bag a furina on day1, i didnt know my pity. And i used to play before but dropped around inazuma so i might have built some back then. Since 4.7. I have completed all the quests, everything except the desert is hundred percent explored, teapot maxed as well. So i pulled on quite a few banners. Yelan, kazuha, kinich, raiden(capturing radiance), nahida, neuv c1, mavuika and arlechinno and i lost every single 50/50 and at 83+ pity every single time. Yup, ive never won a 50/50 ever after i got furina and i dont even go for weapons rn bc it seems even more risky. I feel like the game makes me lose it because I’m an active player and the game knows I’m going to play anyways bc the amount of time and money gone into this is crazy. While if I was more casual player id win some of these 50/50s because they don’t want me to quit.

The 50/50 might be real yes but is there actual proof or are they just claiming its random and we’re all just agreeing. Pls excuse me im losing my mind after losing arle 50/50.
