You’re correctly identifying thermal mass as why they feel cooler to the touch, but this is mixed up in some incorrect and contradictory statements.
The ceramic tiles in your house aren’t really “colder” than you
This is incorrect. Flooring is literally colder, unless your floor temp is above 92℉ (33.5℃). You can measure this with a thermometer. If something is the same temperature as your skin you won’t feel anything - there’s no heat transfer. You could have a copper floor if it was the same temperature as your skin, you wouldn’t feel a thing.
[Ceramic tiles] also have a high thermal mass … they easily lose heat to the air.
These two statements are directly contradicting one another. High thermal mass means it has a harder time losing heat to the air. Given identical conditions, ceramic will take longer to change temperature than fabric. The reason fabric feels less cold is because you can easily change the temperature of it, due to its low thermal mass.

Who do you keep bringing up the quote from the first reply.
They are literally colder than you. But i used the word really colder. The feel colder because of other phenomenon, which we have covered at length and nothing of note was added. We are making the same point, chill out
