You seem to be trying to disagree. I’m not sure with what.If this was something simple, like making a grilled cheese sandwich, sure. But this is a complex skill set. It's like practicing tight rope walking by walking along a 12" wide wall that's 36" above the ground, and then trying to walk an actual tightrope 100' up without a net. There are a lot of in between steps that any reasonable person would take, that for some reason go out the window when we talk about martial arts.
To answer your question, you won't be well prepared. You might not die, but statistically that is likely anyway.
