Yes.
Sometimes bots will camp if it is an important labeled camp point
Like in De_Dust; in the tunnel in the 3-way intersection is an example of a camp waypoint that bots use often.
When I say often; I mean alot.
You can edit map waypointss to add more camp points than normal*green* waypoints, which will offer more options to the bot.
I have noticed when camp points are around their team important waypoint; those camp waypoints are used more often.
It's just an inference.
