Yeah, and I like that - it highlights that he really is a 15 year old kid and he thinks like one, which is why adults (even normal adults wielding super-weapons, e.g. the Shocker) kick his ass.
Comic book Spidey could handle comic book Cap, but in the MCU Cap took him out pretty easily, without hurting him.
I like that Spidey's such a noob, because it means that when we see him grow in experience and improve we'll feel that he's earned it. He's not a hardened veteran who can face down death without fear (like some of the people who fade away at the end of IW) instead he's terrified, as most kids would be.
i like Spidey, always have, and so far MCU Spidey is my favorite.
