Exactly! If they used “carbon dating”, that would mean the stone is “15,000 years old”, unless the people had a “use by” date stamped on the tool itself. I guess the archaeologists get their jollies over things like this, but to me, it’s meaningless.
Quote from the article:
"From 19 optically stimulated luminescence dates of sediments, they determined the artifacts were between 13,500- and 15,500- years-old."

Optically stimulated luminescence
In physics, optically stimulated luminescence (OSL) is a method for measuring doses from ionizing radiation. It is used in at least two applications:
luminescence dating of ancient materials: mainly geological sediments and sometimes fired pottery, bricks etc., although in the latter case thermoluminescence dating is used more often. ...”

IOW, psuedoscience fiction!
