For this reason people who have a basic free developer account are seeing the iOS 17 developer beta already. However, in 2023 Apple has changed this so that if you have any developer account, even if you aren’t paying for it, you can get the developer beta of iOS 17.
Normally the Developer Beta is tied to a paid-for developer account (which costs $99/£79 a year).
It is normal for Apple to release the first beta following the keynote so that developers can immediately start testing to make sure their apps work. The first version of the developer beta of iOS 17 arrived after the WWDC 2023 keynote on June 5, 2023.
