I personally believe that the game protagonists like Red, Gold, Kris, etc, are all child prodigies. In the game's dialogue & story, it's implied that Pokemon training, battling & advancing through the league is actually quite difficult. You can tell that whenever an NPC shouts out "WOW, YOU HAVE TWO BADGES?" Then, consider that most trainers only carry 1-3, sometimes 4 or 5 Pokemon on them, & most of them are early game Bugs, Flyings & Normals.
We only think that Pokemon Battles are easy because we only experience it in video games, in a setting that is handcrafted to help you win. In real life, most of us would have a much harder time, due to training, relationship building, feeding, personal commitments, etc. We'd all be those goobers with 1-3 unevolved Pokemon with maybe a badge or two, if any, that the real protagonist & future champion would beat easily & forget about.
