That is true for engines with double row chains, however single row chains last about 100K miles.
Also, the chain usually is not the problem, but rather the tensioner(s)that often has plastic on it.
I don’t mind the timing belt as long the engine is non-
interference.
Cripes, given your name I’m guessing you know stuffs about cars and things. You’re making me paranoid.
I don’t know if my ‘09 Corolla has a single or double row. I did a ton of research on Toyota Nation and the consensus there is that ‘09 corolla with my engine has a 400k + life unless you hear “the noise.” Which is loud and distinctive.
