What does this mysterious "Luck"... thing even do??!

Did you know, you could change how lucky you are in minecraft? So apparently, there is a hidden luck option in minecraft, both in java edition and in bedrock edition. This option is very mysterious as it only affects a certain thing and doesn't affect most of the other things. SO what does this mysterious option do?!
