each toss is independent of the latter and if the coin had come up heads 9x in a row, the odds of it coming up the 10th time in a row are still 50/50.
if you flip a coin 100 times it might come up 75% heads and that’s not hugely unlikely. But if you flip it 1 million, or 1 billion times, the result will always be very close to 50%.
