There's a special method for getting the first match, which is effectively what
you're after: firstMatchInString:options:range:. In fact, there's another for
getting the range directly:

use AppleScript version "2.4" -- Yosemite (10.10) or later
use framework "Foundation"
use scripting additions

set theText to current application's NSString's
stringWithString:"Human_012345_something_123456"
set myRegex to current application's NSRegularExpression's
regularExpressionWithPattern:"(\\d){6}$" options:0 |error|:(missing value)
set matchRange to myRegex's rangeOfFirstMatchInString:theText options:0
range:{0, theText's |length|()}
set theWord to (theText's substringWithRange:matchRange) as text
display dialog theWord as text

Or even simpler:

use AppleScript version "2.4" -- Yosemite (10.10) or later
use framework "Foundation"
use scripting additions

set theText to current application's NSString's
stringWithString:"Human_012345_something_123456"
set matchRange to theText's rangeOfString:"(\\d){6}$" options:(current
application's NSRegularExpressionSearch)
set theWord to (theText's substringWithRange:matchRange) as text
display dialog theWord as text
