It is also right, a small amount for anybody could be bigger to the other gamblers. But this isn't a problem by the others but ourselves. If we consider an amount as small, then stick to that amount as part of accepted loss and budget when we gamble so that we won't be emotional if we lose it.
Yes, men are in sizes both in real life and in gambling, someone can gamble with $3k on a go and call that amount his thriw away amount that he can risk on gambling, that amount is already a life changing amount to another person and will never want to risk it on a bet for no reasons.
As we have rich gamblers so we have average or poor gamblers both either gamble for the winning or gambling for fun.
