No, one on one tutoring is only marginally more effective than standard education system. As I said, the education establishment has expended enormous amount of effort on figuring out how to teach better, and collected mountain of evidence. You won’t find a lot of d > 1 outcomes in literature, and not many more of d > 0.5. Many of those you find did not replicate, and you should expect at least some bogus outcomes because of how p-values work. Look at federal Head Start assessment, for example: gains are minimal, and they dissipate over time. This is the pattern that repeats over and over in educational studies: either gains are minimal and dissipate, or the study fails to replicate.

What some people are capable of, yes. Does it translate to those people being better at other mental tasks of mental ability? No.

Two sigma https://en.wikipedia.org/wiki/Bloom%27s_2_sigma_problem https://en.wikipedia.org/wiki/Bloom%27s_2_sigma_problem is not a "marginal" effect. And a chunk of that can be explained by mastery learning, which while still hard to scale up is far easier than individual tutoring as a whole. The educational system is not institutionally incented to effectively pursue these empirically workable approaches. It's a matter of bureaucracy-driven failure, not some immutable fact about the world. There's even specifically developed approaches to effectively train and educate those who might be often described as 'low I.Q. individuals', such as "direct instruction". Guess what, they get no takeup from the educational establishment, simply because they're (quite wrongly!) perceived as being demeaning for teachers. The average teacher would rather pretend to educate those who are already highly functionally literate and familiar with educational dynamics (including test taking, of course) and can simply "learn by themselves". Education schools consistently cater to these attitudes and push the same approach.
