Don't ever think like that and bravo for you for taking action to improve like that. It's never too late.

You never know, some girls actually dig that kind of innocence and that makes them feel special.

If anything I have learned from Pick Up is actually to be open about vunerabilities and be okay with them. As essentially the act of approaching a random strange girl leaves one vunerable. And usually I find the sincerity of the approach (Without being needy) is usually what makes it work effectively (At least in daygame scenario - nightgame scenario their other obstacles working against you like AMOGs, loud music and alchohol. But daygame it's all you).

Keep at it, be positive and don't compare yourself to others. Celebrate your progress and how far you've come so far.

And don't worry about not knowing what to do anyways. Most girls don't really know what their doing anyways and just usually starfish and lie there. And if you've watched porn, you know what you're doing
