the probability to roll either H or L is the same since there are 6 possible rolls, 3 are high and 3 are low. you dont have a higher chance of rolling a 4 anymore than you would roll a 2. whatever determines the roll of the dice on the server side; it would be near impossible to decipher, and if it were some sort of RNG...it would certainly be triggered by more than any one set of dice (making it impossible to construct a pattern).
