I haven't checked because I don't have a mac but it really depends if they have decided to increase support life and security updates of the previous macos release.

You don't really need Ventura if your current release is supported a long time.

They don't specify any support life or security lifetimes in advance. Typically what they do lately is update the previous two versions with security updates so you get a couple extra years lagging behind. But unlike MS or a lot of Linux distros there is no support promise and no EOL date.
