OS such as Windows XP -- or most OS, for this matter, contain many, many lines of codes, and so inherit many, many mistakes. Some of these mistakes are obvious, whilst others less apparent, and can take years to discover.
You can think of it as a sort of race, which lasts more than just a few years between those that discover exploits (the mistakes) and use these exploits for personal gain or pure malice, and those who discover exploits and try to fix them with patches and workarounds. Of course, these patches, being codes themselves, also introduce mistakes. Some make the situation worse, others don't. In general, not a pretty scenario.
You are quite right in thinking that the end of extended support means no more security patches. A graphical illustration would be no longer making an effort to fix a sinking ship, and so the ship is doomed to sink and lose in the race between exploiters and patchers.
