How often to cats come back

My cat Katy escaped earlier today about 4-5 hours ago and I didn’t notice and now I can’t find her anywhere on my property. I am actually losing my mind me and my mom are searching for her. She never rarely ever tries to get out of the house. She only successfully did it once and she just slept outside on the porch in the sun the whole time (we have cameras). She usually sleeps with me most nights and she does not get along with other cats which concerns me because we have a lot in our town roaming around. So I guess my question is realistically what are the chances of my cat coming home?
