ELI5: Why can blocked numbers still leave me voicemails?

Because the phone system is still quite outdated. When you block a number, it's only doing so on your phone by simply not alerting you, so as far as your phone carrier is concerned it's no different than if you simply didn't answer your phone, so it brings them to the voicemail system.
