Question About Minecraft Lore

so is the lore behind minecraft real? for some reason im now into minecraft lore (definitly not bc i watched to many shark videos ;) ) so is any of it real? from his videos in one of them he claimed to have found herobrine, and it might be true bc he showed his files or something idk what they are and there were no sus files in them. most of his sightings are on seeds, like null (who you have probably guessed is the skin of this) entity zero, entity 303, and herobrine. he found giant alex in a regular world. now you might think that im just rlly gullible but check out sharks lore videos and you might just see how real they look. i tried to get on his sharkscraft server bc he said in one of his videos about something called herobrine hunters, and i felt like looking more into it, but the video was from 4 yrs ago so when i tried to join it didnt work =(. so yeah and there were a bunch of other things about red sun, blood moon, red steve, green steve, and blue steve too. idk if its all real, so can one of you comment down below and explain what it is?
