How Random is Sims 4 Really?

I dunno, I often let my sims play out their own lives and just watch, and often random things happen between sims. I love how they interact with each other. I may nudge towards a certain interaction sometimes (like if they are insisting on playing video games and not going to talk to someone at the door), but then let them take it from there. I do use cheats because I don't like how jealousy depletes the relationship bars without me even realizing that something is going on if I leave the game running, so I have disabled jealousy, and I hate for my sims to die so I disabled emotional deaths and I avoid putting anything hazardous in their homes, and I don't want my sims to age so in settings I have disabled aging (unless I age them up or down manually). So I guess in that way I do have a fear of certain random events, but that's like real life too because I have OCD and often paranoia. So having some sort of control over the game is good for my anxiety hehe. Especially because I do not have that control irl...
