Don't the 'high-roller' tables have a higher minimum bet? Most people don't start out at the $1 table, and then move up to the high-roller table as they keep losing though. Most people just plop down at a table that has a range/minimum that is right up their alley with regards to their average bet. Then they only really move if there is a reason to (like feeling that this table isn't 'lucky' anymore, or the dealer changes, etc).
