Does marking e-mails as spam help other Mac users?

Sometimes there's a spam e-mail in my inbox. I just have to click the spam button and the e-mail will get moved to the Junk folder. Some emails even land in the Junk folder automatically. I assume over time Apple Mail learns and gets better in recognizing spam and will be better in automatically filtering it. That is right, isn't it? Will marking an e-mail as spam also help other users spam filter? Does Apple has something like a spam filter that learns more the more users mark their e-mails as spam? Or does marking an e-mail as spam only influence the spam filter on my Mac?
