Looks like the light bulb went on for you!!!!
All gaming odds are similar to the following:
$1 slot machine with a 3% house advantage:
You put in $1 and it pays off $1 - You beat the machine for 3¢.
You put $1 in 100 times and it pays off $1 all 100 times. You beat it for $3.
You quit even. You never play it again. The machine will collect its $3 from the next guy or it might wait for even the next guy, BUT, you can bet on the fact that the machine will collect the $3 at some point.
House advantage on slot machines also should not be confused with Hold.
