I think the director was just giving a general estimate of Kong's size, rather than an exact number. He says Kong is "the tallest Kong yet" but only gives 100 feet as a number. Kong will probably be somewhere in the 100 foot range, but I doubt he will only be 100 feet. Plus, this film is set in 1971 and Godzilla vs. Kong will presumably be set in 2020, which means it is possible for Kong to grow during that time. I don't even believe Kong has to be too close to Godzilla's height anyway, just large enough that they can interact and fight for a brief period of time before needing to join forces. If Kong is upwards of 150 of 200 feet tall, he will be big enough to interact with Godzilla.
