Don't believe that. Timing chains do require replacement as well.

Ask him what happens if the timing chain breaks. Does the engine trash
itself, or not? I think Toyota's are the non-interference type which
don't trash themselves. At any rate, that's the important question. It
doesn't matter if it's a belt or a chain. There's still chance for
breaking, and there's still a requirement to change (although a chain
*should* go much farther in theory).
