The cultivation of avocados predates “the gov” by a few thousand years. They were cultivated by native people in Meso and northern South America. Even with a larger seed they have immensely more flesh than their wild progenitors, and the seeds grow just fine. I currently have a 4 meter tall one that’s growing ridiculously quickly that was planted from seed not long ago, and there are two more growing from seed in its shade.
Where I worked in Ecuador we’d find cultivars that had sprouted from discarded seeds all the time and even from fallen fruit on the edges of orchards.
What you have is almost certainly an escaped or feral avocado, essentially an escaped cultivar (a very common occurrence where the climate is right), not a truly wild one.
Unfortunately there is a lot of incorrect and misunderstood information about avocados and both their wild and cultivation history, and that misinformation is repeated ad-nauseam across the board. It’s immensely frustrating that it happens.
