Helpdesk is more people skills then tech skills. Like majority of Tier 1 incidents are pretty easy fixes: like password resets, docking station power cycling, and general application issues that are well known. You may occasionally see a curveball like the CrowdStrike fiasco or other one-off bugs but it you're at a large org hopefully there is a Tier 2 that can help you.
But all this stuff can be learned. If you're a person that can't hold a conversation with people, then godspeed. When I started in I.T around 2017 I came from retail sales (Best Buy/Geeksquad) so I had the social skills down pack and while I had no certs, I held myself in an interview well. At my last job they hired of bunch of dudes who had the trifecta (A+, Net+, Sec+) but man they were some of the most awkward/condescending people in the world.
Like I had people calling my line because they didn't want to work with the Tier 1 team we had because many of them were socially inept. Some of them still message me on LinkedIn to this day begging for me to come back that but that ship has sailed. I really push the social part because people will be calling you because shyt is broken and it's hindering their ability to work. De-escalation is key here because they're going to be mad, not at you but the technology so you will run into a lot of jerks but after you build that rapport and word spreads about you, they'll be relieved that you picked up that call.
