It appears that you might be drawing a distinction between what is commonly known as "book smarts" versus "street smarts."
Compare to a Harvard-educated CEO who may have been raised in privileged, insular surroundings - yet intelligent and educated enough to run a successful business. He might be able to thrive in circumstances of fair and lawful competition (which relies more on reason), while the drug lord requires a somewhat different skill set in order to thrive in circumstances of unfair and lawless competition (which relies more on brute force).
To some extent, yes, but 'street smarts' sells it a bit short. I'd say real-world smarts, or perhaps wisdom.
Book smarts often fail in real world situations, for example:
Long-Term Capital Management - Wikipedia
Many "less intelligent" traders make money because they understand markets and people and how to avoid being a sucker, real-world smarts, yet couldn't begin to understand the complex formulae of mathematical quants.
You might be able to quantify certain types of reasoning ability in a vacuum, but better reasoning ability also enables you to reason your way into holding stupid beliefs, and reason your way out of accepting any evidence that you dislike (see cited scientific studies above).
"Intelligence" also makes it easier for us to acquire and apply false information (anti-knowledge).
"Intelligence" is not wisdom, and wisdom is the only thing that really counts whether it comes from experience, intelligence, common sense or something else..
There is no rigorous way to quantify intelligence, just arbitrarily selected mental capabilities.

Book smarts also makes it easier for us to acquire and apply false information (anti-knowledge) which is often more harmful than ignorance. They are only helpful if you were trained correctly, or if you have the wisdom/smarts to identify and undo bad training.
IQ "intelligence" is not wisdom/real world smarts, and wisdom is the only thing that really counts whether it comes from experience, intelligence, common sense or something else.
However, there might be other factors involved, such as in the example of a drug lord. A lot of what they do may be more in the realm of physical ability and emotional/social intelligence. They may face combat situations which can test an individual's ability to stay cool in a crisis or something of equal magnitude. I don't know that such a skill involves raw intelligence, or if it's due to a more emotional component.
That's the point though. To be a successful drug lord you need both masses of real-world intelligence, and the qualities/nerves/ruthlessness to survive in the criminal environment. You need all to be able to thrive.
To be a great politician, you need masses of real world intelligence, and also the vision and political skills to be successful. Even then, a great peacetime leader might not be a great wartime leader.
In UK pre-WW2 there were countless ferociously intelligent MPs, yet most wanted 'peace in our time' and appeasement. Churchill was pretty much alone in his insistence that this only made things worse. This isn't because he had a higher IQ than everyone else, but because he understood
this aspect of the real-world better. He was a great leader because his skillset fitted the environment. Had he been born 60 years later we might well never have heard of him. That is why simplistic standardised "intelligence" metrics are worthless in a complex, non-standardised world.
IQ doesn't measure independent thought, vision, foresight, opportunism, the ability to be a risk taker/risk averse in the right situations, creativity, and countless other things that are generally far more important than "IQ intelligence".
It also can't legislate for people who are below average at most things, yet excel at one thing in particular. When choosing someone to do task A, I'd prefer someone who was excellent at task A, yet awful at tasks X,Y, Z, rather than choosing someone who was slightly above average at tasks A, X, Y, Z.
