"A high general intelligence implies mastery of life itself"

It increases the chance, but "implies" is too strong word here. High IQ doesn't magically overcome all obstacles.

How easily can you overcome isolation, that depends a lot on what opportunities you have. The same opportunities don't exist in every city, or every country. For a high-IQ kid it can make a lot of difference whether other high-IQ kids live in their neighborhood, or in their school.

For example, most of my teenage socialization was in a local math club. Well, it was a lucky coincidence that the math club existed in my city. (And another lucky coincidence that I knew about it.) Without it, I would have to settle for an option that would fit me much less. I know because I tried to find other places to socialize, and they just weren't as good for me.

Online communities can be great, but it's not the same as also having an offline community. Imagine a small forum you like. How much better would it be if those people lived next to you, so you could e.g. go for a trip together. Well, some of them probably happen to live next to people with similar interests, and some of them don't. Luck is an important component here. (Yeah, as an adult you could move to a different city. For a teenager this is less of an option.)
