I can say a winning player if he can break even in a given time- say 3 months.
His wins would be those accumulated points and status level.
You can't be a winning player if you only break even unless, I guess, you are playing at such massive stakes that the player points you gain are wonderful.
Other than being in the black, regardless how you got there, here is some good advice...
"You got to know when to hold 'em, know when to fold 'em,
Know when to walk away and know when to run.
You never count your money when you're sittin' at the table.
There'll be time enough for countin' when the dealin's done.
Now Ev'ry gambler knows that the secret to survivin'
Is knowin' what to throw away and knowing what to keep.
'Cause ev'ry hand's a winner and ev'ry hand's a loser,
And the best that you can hope for is to die in your sleep."
Just about sums it up
