Why do you want to force your kid to study? Kids are naturally curious, it's likely that your kid will be curious about something. Introduce them to study and scholarship as a means of figuring these things out, so that it becomes natural to them.
You need to repeatedly solve multiple practical problems to internalize the knowledge. And you'll eventually need to do stuff that you don't really like at all.
Just a week ago mine found and devoured a pack of cookies that were meant for supper and then cried at supper that there weren't any cookies left, choking on a hated apple instead.
Guess he won't do it again in a week if there's another pack of cookies in the hand's reach? Guess again!
This was famously tested with the Stanford marshmallow experiment. A sizeable fraction of kids - preschool kids, no less - can in fact learn not to eat the marshmallow.
There are millions of people struggling to get on a diet, to quit smoking, to stop doom-scrolling their choice of social media. Most of them know very well how good it would be to stop doing bad things and start doing something good instead, and yet they don't.
Children are worse, overall, because life isn't as harsh for them as it is for adults. An alcoholic who can't quit drinking is risking his marriage, his career, on top of his health, and still pulls out a stashed flask and takes a sip. The worst that can happen to a child is that their parents will yell at him / her? That's a very weak deterrent against doing something that offers instant gratification.

This curiosity extends to simple facts (like "who's the best soccer player: Messi or Ronaldo?") it doesn't help with important subjects that need studying (like, how do you prove Pythagoras' theorem).

Children simply don't "work" like that. If you let children "figure things out", they'll "figure out" if Messi or Ronaldo are the best soccer player, and they will never even ask why is the sum of squares of the catheti equals the square of hypotenuse. Not only will they never ask that, they'll never figure out there are right triangles. Some discoveries in human knowledge took us many generations to make and some are trivial and easily discoverable. The former is difficult for people to learn. It requires effort that doesn't result in instant gratification. It's boring because often you will have to read the same thing many times over. It's frustrating because even after having read the same thing you still might not understand it. You have to be a masochist to like doing that. Generally, people who do it, don't do it because they like it. They like the side effects (eg. you may like to be paid a professor's salary, and so you'd grind the subject you want to be a professor in).
So, it never becomes "natural" to anyone, especially not to the children outside of the very few very simple things one might learn in this way. Left to their own devices, maybe half of all the children would love to become YouTube influencers who make their living by streaming the video games they play. They'd never even consider becoming an accountant or an engineer. They wouldn't even know accountants or engineers exist.
