It all depends on how things are organized. If each object needs to run logic every frame, you can start to run into severe performance issues way before you get to 10k. 60fps means you have 16 milliseconds to check everything in the scene. This can be a lot of time but you only have to make one small mistake to lose any advantage.

We have to reach for data oriented techniques like ECS if we want to keep the CPU ~idle while managing 10k+ entities in the scene. This stuff is a big pain in the ass to use if you don't actually need it.
