This has been on my mind recently as someone who was in the front office for a few years (but not making trades) but is now on the outside.
I mean each day 100's of Phd's start with clean market
data, more data sources than you could possibly think of
and statistical back testing systems that have 1000's of
man hours put into them, trying to find a way to make money.
It seems to me that the Tiger Rule applies here. You don't have to outrun the tiger, you just have to outrun your buddy.
Is the choice really that one can be in the cohort you mention, or you can buy an index fund (or whatever the equivalent is in the market you're interested in)... and that's it?[1] Is the market so efficient that there is no middle ground where a smart and methodical person can make more money than the index plodders without being obliterated by the big players?
That seems really unlikely to me.

Don't think in terms of there being one tiger that stops as soon as it gets something to eat. The market's more like a sea full of countless sharks, where all the sharks have to survive by eating other sharks.
You're not wrong to think that, if there's any way to consistently make money by trading, it's by exploiting inefficiencies in the market. But remember that those inefficiencies come from people. Are you confident enough in your skills, your education and your resources to be sure that you'll be one of the ones finding and exploiting inefficiencies, rather than one of the ones who's creating inefficiencies for others to find and exploit?
you can make more money, you just have to take more risk, and it takes being quite knowledgeable, experienced, and careful to know what a good risk is and how to diversify it/hedge it.
