Even Starship's exact payload capability isn't set in stone just yet (the stated numbers are targets requiring optimization of the design beyond what the current prototypes have), nor is the amount of refueling needed. Even the fuel transfer system hasn't been concretely settled on yet. While they are working on catching, there isn't enough certainty on its reliability (particularly for the ships).
Hell, as it stands it isn't even clear if initial vehicles will need auxiliary thrusters to avoid digging up a hole upon landing. Even NASA seems to be uncertain about that one.
So yes, it is ridiculous to argue that they aren't serious about setting up a colony based on what they're doing right now.
Beyond that though, they're working on the spacesuits (granted, they're so early into that they're nowhere near ones usable on Mars) and they have demonstrated the ability to perform some amount of important maintenance on the Starship vehicles without needing machinery that isn't easy to bring along.
