bad analogy time
Imagine the entry hall to an apartment building that has 200 units. 200 post boxes on the wall. Behind 199 of them are shredders that destroy anything put into them (no one lives there). Don't get the address wrong on your letter!
(i.e. when you're sending crypto).
Now imagine the instructions on how the posty should decode addresses is in the first letter he delivers.
Multiply by a million. That's how safe this whole industry is.
