Why do all the bad builders think they are amazing

I am posting this again because last time I don’t think people were understanding what I was saying.
I play on Xbox and whenever I post a group post looking for (GOOD) builders they are always 9 year olds who think they are amazing at building. I usually try to be as kind as possible and maybe give a few build tips, but i am just starting to get annoyed with how many people think they are the best builders on planet earth when there builds are around the quality of the diamond house you build in creative at 5 years old. Then when I try to say anything about how it is just annoying I get flamed for being rude.
