No, this wipe will not affect your data.
You're in a situation where your system is running a non-LTS version of Ubuntu while you're using an LTS release. Updating might be necessary for security and support, but it's not guaranteed to affect your data unless you've backed up everything first. Consider your backup strategy before proceeding.
However, if you upgrade, ensure you have backups, since an update could potentially erase data or cause issues.
