I sure hope so as well, but usually iOS versions with actual beta builds (that is, not a 0.0.1 "hotfix" release) come about 4-10 weeks apart. There is a chance that this "0.0.5" release is meant to be fast-tracked through the release process, but this kind of thing is rare anyways so I can't say much about it. As of today we are on developer beta 2 of iOS 13.4.5.
I remember working with an individual that stated in a public mailing list that an OS X version was going to gold master. This person was subsequently fired for releasing that information. How things have changed.
Most people make these statements as an external third party who have never worked at apple or similar.
They've just noticed that apple releases stuff on fairly strict schedules and predictable behaviors, so it's easy to predict when the next minor point release will come out, based on previous behavior. Similar with a new iphone releasing every year after july at the very least.
