Short answer: yes indeed.
Back years ago, you may only have understood people in your region, without learning to understand other parts.
Then along came media including Raidió na Gaeltachta. Unlike many languages where people want to speak the “central” dialect, native speakers will speak in their own accent and dialect on Raidió na Gaeltachta.
So they’re trained in to understand other accents.
Moreover, they will understand standardized Irish. Plus they’ll be happy to hear you try! You’ll get friendly smiles in your direction.
