No, there is still a 50% chance I will be tortured. There are a 101
identical copies of me running and they are all me, eventually the
copies open their envelopes and one of them sees something the other 100
do not, it says torture. He is still me but now he’s different from the
other 100, he has diverged. So now there are 2 of me, the tortured copy
and the other identical 100.

No. If 6.02 *10^23 identical copies of you had a winning lottery ticket
and one did not then there is a 50% chance you have won.
