Here, time, space, and people refers to what/whom you hold in your mind more than the actual physical reality differences or the actual people around you.
Since your conscious experience of reality is mostly only from what/whom you engage/invest/attend to in your mind.
A timeline for your life can be charted out with these 3 variables,
Marking out the broad episodes and flow in your lifetime till date.
A diagram might look something like this say:

I wonder if this time-space-people position is some sort of destiny, or prewritten to some extent.
Is it prewritten that we would be at this particular time-space-people point now?
Is the overall map of our life already charted out in a vague way?
In terms of where and whom we’d be with in our minds at a certain time?
In our lifetime we may meet around a 1000 people?
1000 in proportion to 7.5 billion is like ‘7.5 millionth’ of the world population.
That means I would have to live 7.5 million lives interacting with 1000 new people in each life to cover the whole population?
And how much do we even understand the few people around us? (let alone the 1000 people we may roughly know).
We may reach some depth only after many years with a few people, that too only if we keep up the intensity.
Imagine the varieties of experiences possible.
