How do I learn Halo Infinite?

[Dark Sun Gwyndolin]

Title; I've made a few attempts to get into this, but every time, I get obliterated by players with infinite power weapons, invincible vehicles, and perfect map knowledge. Is Halo Infinite just a really deep game that there's a trick to get good at, or have I gotten really unlucky to constantly find myself spawncamped?

The question is not why do I suck, but rather, why are the MLGPros never on MY team? Every match I've played has been a one-sided blowout. I've attempted to adopt tactics like sticking with teammates and watching my minimap, but it doesn't help; the enemy just kills my teammate, then me. Is there a mode that's more beginner-friendly?

In other games, you get better by playing more due to experience.

In Halo Infinite, you get better by playing more due to eventually hitting a lobby where you are assigned to fight a team comprised entirely of people who have never touched a video game in their entire lives.
