Is this supposed to be a good thing in a game?
Absolutely. Maybe not for a sport, but unless you're talking about the pure competitive aspect of it, most games benefit from having that level of accessibility. Bad players need to feel like they can win games. Even if they don't know how, they'll feel like they can win again.
One of the big draws to any game is the idea that you aren't just measuring your skill/experience at the game against everyone else playing, it's like when everyone comes over to play Super Smash Bros but you can tell the host has been playing on his own to practice, it takes a lot of the fun out of it. You can also use the example in SSB of playing with items on. Sure, really competitive players will hate the randomness that comes from items but the whole point of that randomness is to give everyone else a fighting chance.
I guess it depends on what you want out of a "game". If you're only looking at it through the lens of Chess where luck is virtually nonexistent and skill is the ultimate deciding factor, you're going to take a lot of issue with anything that upsets that balance. But, in practice, most people play games for enjoyment, not for sport.
