Does it mean the same as "Don't worry"? Is there any difference between those two sentences?

That's a great question! While the mean the same thing and can be used interchangeably in a casual context, they do have a difference - formality. "Don't you worry" is very informal because it has a personal and familiar tone, something you would say to a friend or family member. For example, it would be considered impolite to say "don't you worry" during a job interview, but "don't worry" is perfectly acceptable. Ex: Don't worry, I can handle a long list of tasks easily. Ex: You're moving next week and your car is broken? Don't you worry, I'll help you move!
