Thomas IIRC was reporting on something Harry had told him. Thomas does have a small bit of genuine magical ability. More than most Whamps have, because most Whamps have none. There are Whamps with more, but none are terribly strong with magic.
I suspect either Thomas was misunderstanding / misreporting, or Harry lied to Thomas in order to boost Thomas' spellcasting abilities (because self-confidence is a huge issue in order to cast spells).
Now, it's also true that there are some rituals that need zero "magical talent" to perform. They've been described as "vending machines" -- you go through the correct steps of the ritual, and your result pops out; zero "magocal talent" needed, the most pure-muggle people can perform these rituals successfully (creating a circle/ward is one of those rituals; so (evidently) is the HHWB-summoning by the porn-star sorceresses (or at least, parts of it)). So -- from that POV -- it's also true that "everybody has some magical ability." Harry could have spoken in this sense; again, that presumably would have been to boost Thomas' self-confidence (but without technically lying to him ("Darth Vader betrayed and killed your father, Luke!" -- "From a certain point of view..." ) ), so Harry could teach Thomas a few small spells (specifically, for that short-story, IIRC Thomas used the tracking spell).
