Which categories do these go in on parent guide?

I sometimes used parent guide but often I am confused on some topics and where they go on the parent guide.

Suicide

This one often confuses me whether it should go in violence and gore or frightening and intense scenes. In this case I am referring to someone doing it without any detail as I often see it in just violence and gore rather than frightening and intense scenes or both.

Gambling

This one is more about when we should put it and when we shouldn't things related to 'gambling' in the parent guide, as it can include many things such as:

• Themes/focus related to gambling/gambling addiction
• References to gambling/a gambling addiction
• Gambling appearing in the background (example: the background shows someone on a slot machine)
• Particularly to video games, simulated gambling and loot boxes

I would think it would be classified under frightening and intense themes but I might be wrong. Also I just want to know whether we should include these.
