This is true, but there is always exceptions. The second paper I published I sent off to the journal and after a couple of months I had not heard anything (this was in the physical paper days where you had to mail everything). My supervisor decided to call the editor to ask what was happening. The editor said "oh we published it last month". The whole paper had gone straight through without a single change. This of course was the last time I ever had a paper accepted like this :)
