"Any" vs. "Unlimited" tonnage question

Question: As per the info below, do the words “any” or “unlimited” make a difference in the requirements for the Mate opening on the Staten Island Ferry? If so, can anyone state which USCG regulations defines either usage?

On the Official NYC jobs link for Mate (ferry) Job ID 174405:

https://a127-jobs.nyc.gov/?jobPath=psc/nycjobs/EMPLOYEE/HRMS/c/HRS_HRS.HRS_CE.GBL?Page=HRS_CE_JOB_DTL&Action=A&JobOpeningId=174405&SiteId=1&PostingSeq=1

It states:

"License Requirements
All candidates for Mate must possess at the time of appointment:

  1. A valid United States Coast Guard license as Inland Mate of Steam or Motor Vessels of [B]any gross tons or a superior license…[/B]"

And on the link from the Notice of Examination for Mate (ferry) Exam 5006:

http://www.usmmaaf.com/s/1175/images/editor_documents/mate__oc__-noe__5006__oct_2014.pdf

It states:

“a. Mate of inland self-propelled vessels of [B]unlimited tonnage, or superior[/B] [B]endorsement…[/B]”

The old wording (before March 24th 2014) was “of any gross tons”. The new rulemaking changed the wording to “of unlimited tonnage”. They mean the same thing…
