Will signing out of my Apple ID, temporarily, remove my photos?

So we set up a screen time password for our iPad, which is logged in to the same Apple ID as our parent’s. We forgot the password for the screen time, so we’re trying to reset it. Everyone on here says the only solution is to reset the device, but I saw one involving logging out of the Apple ID. Now because of the restrictions caused by screen time, we can’t log out of the Apple ID on the iPad. Our last resort is to log out of the Apple ID on our parent’s device (with their permission), so we can change the screen time password on the iPad instead of the phone. So if we log out of the Apple ID on the phone for a short time, and then re-log in, will the photos on the camera roll still be there? We don’t have a Mac, or any space on the cloud. Everything is on the phone.

TL;DR, Will logging out of the Apple ID, then re-logging in soon after, remove all of the photos on the phone, or will they stay there? Nothing saved on iCloud or photo stream.
