no offence but you guys really don't understand math at all
every single roll is random, and every next roll does not remember the previous one
a seed gives u line of infinite amount of numbers which can be actually bad or good for you depends on luck
changing a seed will give u other line of numbers which contains other rolls, but still they are random.
Let's say you rolled 20 reds in a row 2x payout, it was 100-120nonce on your seed, you change seed to get better and actually you just met up with a seed with 20 first nonces are reds for u...
This is all RANDOM
