Generally true, although some species need way more attention than others. And 'way more' can often mean full time attention whenever they aren't sleeping.

I had an Amazon parrot that needed less attention than an African Gray or a Cockatoo.

I'd still not recommend as a pet given that their lifespans are so long. It's a decades long commitment and they may even outlast you, in which case you need to figure out what's going to happen to them.
