No. You can get results WITHOUT developing your senses, but doubting whether or not you even made contact during the ritual, due to a lack of senses can cause you to fail.
As in, I don’t think as many people fail at evocation or even gom rituals as think they do. I think they fail to notice any signs they were heard- it could be as little as a glowing orb flash of light that you blink and is gone (energy or spiritual), the room temperature changing, chills on your skin, pretty normal/subtle things with all the nervousness of trying to get shit right…
and if you miss it, think you didn’t even make contact, well. Lots of people don’t follow through with the rest, or doubt so hard they were heard, that why should the entity bother? They can take your offering, or feed off you or whatever and you have no idea…
So use a safe system, a gom book, something like Luna, actually work on developing your senses but, if you go into ritual prior to being able to sense spirits- treat it like you were talking to an invisible friend 100% of the time, until it’s not just an invisible friend.
It’s just my opinion, but when I’ve helped people in the past that thought they failed at evoking or simple rituals, those that changed their outlook from trying to get confirmation they were heard to assuming they were heard, began to see results shortly there after.
That’s not to say it doesn’t take time. Most of the shit we want when we first start is way more complicated than we realize, it’s the reason we come to magic- because we can’t figure it out any other way and well, those things often take a year or more, so I really encourage people to work at the whole of their life and not just whatever that one reason is.
Make thyself better as a whole, and things flow into your life easier imop, and you don’t worry about the magic nearly as much.
