Trump "confirms" so many things, but few of them are true. None of Iranian Kurdish parties have confirmed receiving arms.
The absolutely only instance I have seen of protesters in Iran being armed with firearms (and I've watched a lot of footage), was a day-time protest in the Kurdish-majority mountainous borderland. Since there was a risk of authorities spilling blood, 4 old guys (appearance well over 50 years of age) in traditional clothing were present at a protest in an open area, carrying hunting rifles which looked older than the guys. They could have, theoretically, bought time for others to escape by offering some counter-fire for a minute or two. But on that protest, authorities did not attack. Probably because the whole town was Kurdish and cops decided to stay home.
Also I apologize for re-posting, but:
Kurdish Iranian opposition groups deny claims of receiving weapons from US
Mohammed Nazif Qaderi, a senior official from the opposition Kurdistan Democratic Party of Iran (KDPI), told Rudaw that “those statements made are baseless and we haven't received any weapons.
/.../
Kako Aliyar, a member of the leadership committee of the Kurdish Iranian opposition party Komala, told Rudaw that "as our own party, no weapons have come to us and we haven't received anything, we're not even aware of the matter.
/.../
Amjad Hussein Panahi, head of communications for Komala of the Toilers of Kurdistan, also told Rudaw, “We assure you we haven't received a single bullet or weapon from any country or place, and we're not aware of the existence of such a thing; what we have is our own.”

Hamno Naqshbandi, a member of the general command of the Kurdistan National Army affiliated with the Kurdistan Freedom Party (PAK), said that “Donald Trump's message is unclear to us. What is there is that we as our army have in no way received weapons from the US or any other country, not even a single bullet."
