Well, just no. If you played at 49,5%, statistically and probably your next roll will be a loss 50,5% of the Time. Like every roll of you was before. There is no "memory". Whats so hard to understand about that?

Statistik and probability like this only work when you look in the future.

The probability for loosing 6 Times in a row is ~1,65%, but if you already have lost 6 Times in a row it is still ~1,65% for loosing even another 6 Times in a row.
