Lean towards free to play.... means you don't spend much. Anyone who's never spent a dime on Hearthstone but buys the $5 Welcome bundle only, for example, leans more towards being f2p. Too difficult to understand? I shouldn't be surprised considering you think 'f2p' is a "word".
You misunderstand your own words :)
You can’t ‘learn towards’ a zero sum. Look it up dummy.
(Or repeat your mistake again and again and be laughed at. I would look it up if I were you.)
If you spent $1.50 in 2014 to buy an arena run and haven't spent anything since, does that really make you significantly different than a ftp player? Not really. Can you claim to be a ftp player? No. Can you say you are practically one? Yes.
