I agree with you, if we play gambling for entertainment purposes, usually do not think about fairness. So we don't need to check
every bet we have done to find out the fairness of the gambling site.
Even if we are just Playing for Fun always consider the fairness because We are spending money here so it is deserving tobe fair and legit.
Because chances of winning is always there and we might win the jackpot if very lucky.
Moreover, we do choose gambling sites that are popular and
trusted, so gambling sites reputation is guaranteed well. Because gambling sites have a good reputation, I believe they will be fair,
so there is no need to verify fairness.
Well not all are there to find reputable and popular site sometimes we are aiming to try newer gambling site for experience and other entertainment place to enjoy.
