TFL says daily ridership is 5MM people, and based on your figures, daily advertising revenue is 390k GBP. That means that for every 1000 users, they're earning 78 GBP in ads revenue.
From my experience on the tube, I see maybe 10 unique ads in a given day (sometimes less, sometimes more), which means that CPMs on the tube, for an untargeted audience, are about 7.80 GBP. That's a huge number!
(As an aside it's trivially explainable by the fact that on the Tube you are basically forced to look at it, likely for 10-20 minutes. You either stare at the person opposite, or you look up, where oh, there's a convenient hair loss advert).
What matters is whether the person being forced to look at the shit gets a good deal or not.
They don't. I get _nothing_ from an advert on the street, and from an advert on the tube I get a discount of pence, which could _easily_ be made up for in improved mental health outcomes.
You've even quoted it.

So 7.8p per person. It would disrupt my day less to pick that up off the street. That's not a joke, it's serious.
You think it's a lot, because you're mentally multiplying (it's already in this bloody euphemistic "CPM" term) by loads of people and imagining how much you can make from mass abuse.
Funny, and true.
While reading the parent post, I found myself imagining Mr. Burns from the Simpsons rubbing his hands together as he considered what an awesome 'CPM' he was getting.
Like you, I also think some concepts are bullshit and totally deserving of willful ignorance.
I don't know what CPM is either, aside from an OS I used 30 years ago, but if it makes advertising seem reasonable or desirable, I'm sure I don't want to know.
I suspect that's 5 million journeys, not people, and it's tube only, not all TFL as a whole.
£390k a day of advertising income, and £13m a day of farebox revenue, means that every £2.60 ticket would be £2.68 without the barrage of adverts.
- TfL gets ad revenue from buses, bus stops etc., so almost all ~9MM Londoners see their ads every day
- you might see 10 ads in a day, but they're much more eye catching than online ads, due to position and size, and the fact that an average tube journey is about 50x the time we spend on an average web page
- ever sat in traffic behind a bus? those ads are targeted at people who own a car, live in London, and speak English
