Yes, but they don't do it with 70000 separate processes (or "address spaces" to use the 390 terminology). They have a few processes/address spaces accepting a transaction, processing it, and spitting out the result. (Or, in some cases, accepting a transaction, processing it, issuing an async disk I/O requerst, and then doing another transaction while the first disk I/O waits). (Think of, say, a Web Server, which might be providing service for thousands of simultaneous clients, with just a relative handfull of web server daemon processes running.)
I don't think 70000 Unix login users, or 70000 TSO users, or 70000 processes/address spaces of any kind, would fly.
Not that I have a problem with 32 bit process IDs.
