OP explicitly asked about himself, not some government organisation.

Not necessarily. It might even be an overestimate if the attacker fails to supply enough nodes of the right kind.
>So almost certainly thousands of people
We're talking about a targeted attack. Of course the statistics game works better when you don't target specific people and just fish randomly. But there are probably more cost effective methods as well.

From OP: " I can't target a specific person, but eventually I can find someone who has all three bounces through tor nodes I control, no"

Assuming they match the existing distribution of nodes, they will only have better results.
