The word "high-rollers" is often synonymous with gambling, casinos, and luxury. Its antonyms, on the other hand, represent the exact opposite. They can include words like low-stakes, penny-ante, penny-pincher, and frugal. These words describe people who don't indulge in life's luxuries or take unnecessary risks. They are often associated with humility, practicality, and financial responsibility. However, these antonyms shouldn't be mistaken as a lack of ambition or drive. People who prioritize financial security can still be successful in their own way. So, while high-rollers might get all the glamour and show, those who are careful with their pennies may be more responsible and pragmatic in the long run.
