How to secure my Apple ID from uninstalled apps on my iPhone?

My understanding of “uninstalled apps” are apps that have been previously deleted from your IOS Device..That said, Apps listed in this category are Apps currently on my device, that I’m using. I haven’t deleted them.

I have however been dealing with some Device/Apple ID issues from a breach. I haven’t been able to determine 100% where the other devices are connected other than previous Family Sharing. Could these apps be from one of those devices? Or from one of the devices that were purchased on a previous account without my knowledge?

Thoughts?
