The idea is not for a single fighter to be a match for the Enterprise, but a squadron of them could be quite troublesome, as shooting one down leaves the rest to continue their attacks.
Sure. And if we apply this back to their respective eras:
TOS: All fighters shot down before they can get close enough to attack.
TOS Movies: All fighters shot down before they can get close enough to attack.
TNG+: Some fighters shot down, but some are able to attack.
DS9: Few fighters shot down before most fighters are able to close to attack.
