Once you've reached a certain number of rolls without a five-star, the percentage chance that you'll pull a five-star starts to exponentially increase until it caps out at 100% at 90 (80 on the weapon banners). For Character Banners, Soft Pity starts at 74 wishes. The Soft Pity for weapon banners starts at 64.
It's the pity vote. 50/50 means when you hit the pity vote there is a 50% chance you will get the event banner character (example Hu Tao) and a 50% chance you will instead get the regular permanent 5 stars (example diluc, mona, qiqi, kequing, or Jean).
Does Pity reset after a 5-star pull? The counter will reset whenever you get something of that rarity, meaning if you get a 5-star at pull 59, it'll reset to zero. This is completely random, and there is no way of controlling it. Pity resets every time you get a 4 or 5-star pull.
On the limited banners, you are guaranteed a 5-star on your 90th pull if you do not get one within 90 pulls. Once you get a 5-star character, this 90 wish timer is reset. Furthermore, there is a 50% chance that you will receive the limited 5-star character on the limited banner.
