Imagine you have 20,000 coins, and you’re going to flip them all. You’ll very likely get something very close to 50% heads and 50% tails… but every time you flip the set of 20,000, you will not get the same outcome of heads or tails *on the same coins*; The first time you flip them all, coin 205 might come up heads, but it might come up tails the next time.
Identical twins have the exact same coin flip results throughout the set (rather, you just did a single set of flips, and gave the results to both of them). Other siblings including fraternal twins are the result of separate coin flip sets, so even if you are starting with those same 20,000 coins, they will turn out differently, and it’s incredibly unlikely that you manage to copy an earlier set of flips just by chance.
