The age that these groups claim to find is usually on the order of thousands or tens of thousands of years old.The particular example you bring up is one of the most famous such cases.
Now, it is known that $^\text$ decays at a fast enough rate (half-life ~6000 years) for this dating method to be absolutely useless on such samples. would not have been able to obtain this sample, had they been honest about their intent.
He said that his team and the laboratories they employed took special care to avoid contamination.
That included protecting the samples, avoiding cracked areas in the bones, and meticulous pre-cleaning of the samples with chemicals to remove possible contaminants.
] Carbon-14 is an isotope of carbon, with carbon-12 being the primary isotope.

The main point of the debate seems to be the following: Over the past decades, several research groups of self-proclaimed creationist scientists have claimed discoveries of dinosaur bones that they have managed to date, using radiocarbon dating methods, at some age which is a lot below the 'usual' i.e.
mainstream accepted date for the age of these bones (several dozens of million years old).
Dinosaurs are not dated with Carbon-14, yet some researchers have claimed that there is still Carbon-14 in the bones. Do these data indicate that a more accurate method needs to be derived?
What solutions are available for increasing accuracy of the tests? From the source linked above: Carbon-14 is considered to be a highly reliable dating technique.
The theoretical limit for C-14 dating is 100,000 years using AMS, but for practical purposes it is 45,000 to 55,000 years.
If dinosaur bones are 65 million years old, there should not be one atom of C-14 left in them.
Knowing that small concentrations of collagen can attract contamination, they compared precision Accelerator Mass Spectrometry (AMS) tests of collagen and bioapatite (hard carbonate bone mineral) with conventional counting methods of large bone fragments from the same dinosaurs.
