A thought crossed my mind while playing Minecraft. It's probably a stupid question but whatever.
Does chance depend on time?
When I start a new world, a random seed is generated, but what if I wait a second before generating or what if I close and reopen the game and then generate it.
Would the generated seed be the same no matter what?
Same goes for a coin toss or something. How does time influnece the outcome? Or rather how do other variables change when time passes?

Time has no baring on the probability of the situations you gave. I'm assuming minecraft has a random number generator to create a seed. Now, the maximum amount of seeds possible is 18,446,744,073,709,551,616 (2^64)

So, the sample space (total possible outcomes) is that number above. To get the probability, you divide 1 by the sample space.

For the coin example, again, time has no baring. There are two outcomes, heads and tails. So H and T. You divide one by the sample space, so 1 (one of the outcomes) by 2 (total amount of outcomes) to get 0.5

Let's say you want to know the odds of getting heads twice in a row, which is HH. The total sample space is then 4, as the collection for the sample space is {HH, TT, HT, TH} so simply divide the odds of 1 outcome occurring in that sample space, 1/4 = 0.25. So a 25% chance of getting HH when flipping a coin twice.

Time is not a variable in probability unless you introduce it, which you didn't do, but that's another discussion altogether.

Time doesn't influence RNG unless your RNG is built to take time into account (like most seeding systems are since time is convenient "random" number to use for various processes)

the seed generator would have to run continuously

Not at all. The current ISO standard requires that every random number generator
produces the exact same number every time it is called.
This is fine and it works, as long as this number is actually random.
