Does it get better?

I have been playing Genshin for about 2 years, starting with Keqing, and this is my character pity luck so far. I have seen my friends and a lot of other people get characters and win 50/50 in less than 60 pulls every time or get double 5 stars in one 10 pull. But yeah, to anyone who has gone through something like this, has the pull rates and luck gotten better overtime?

Also in between Yoimiya and Nahida I lose 50/50 to Jean with about 80 pity as well and Nahida is somewhere around 70 pity. The rest are accurate.
