The doesn't mean the the point they were making isn't true. Any game is going to have characters who are both strong and easy to learn, thus in some ways making it difficult to justify playing a more complex character.
Not everyone plays fighting games just for the sake of winning. Some people play fighting games because they find a character which connects with them and allows them to feel like an extension of their body during gameplay. When anyone reaches that level even if they win or lose they had a chance to express their gameplay which renders all that effort went into learning that character worth it.
But if you're talking about that 0.00001% of the fanbase whose livelihood depends on winning in said fighting game then your point is valid.
