Can dataset getTotalCount() can still count more than 1000 items? THANK YOU

Hi the code below will query and count the numbers of items even if it is more that 1000,. but counting using dataset getTotalCount(); will it still count the data even if it is more than 1000?
Based on my experience datase count displays result faster than using a wixData query. If may I ask your experiences with regards to my question here, I would love to hear from you.

THANK YOU SO MUCH!

Have anyone tried using dataset getTotalCount() on a dataset with more than 1000 values? Thank you
