I don't think it's very accurate. I asked it the chance of losing at least once out of two 50% rolls. There are 4 possibilities: WW, WL, LW, LL. 3 of the 4 involve at least 1 loss, so the correct answer is 3/4 or 75%. But it somehow came up with 5/8 or 62.5%:

As soon as you decide to put a large bet on a small cash-out value, there will certainly be a red value that is less than what you thought. Maybe this is a psychological attitude I do not know.
The crash point of each game has already been determined. You deciding to place a large bet changes nothing about the crash point. You can prove this to yourself by checking the past results. Each game's crash point is completely determined by the hash of the seed of the following game.
I know that an each bet does not depend on another
This is true.
If an event (in this case, a bust at 90x) does not occur during the time during it usually took place, then the chance that the event will occur will increases.
This is false. It directly contradicts your previous statement.
