No. Expecting traffic from Google to a product page is rarely going to convert.
Think about it. If they're smart enough to Google, they're smart enough to land on a site like Amazon and Walmart or even Aliexpress where some seller is beating your price down by 100%.
You're also competing against Google Merchant Centre Ads. So your viewers have a product comparison right in front of you.
With shopify or e-commerce in general - inbound marketing rarely works. You need interruptive outbound approach. You have to lure the customer to your site. You have to bank on their impulse.
With that said, it is also important to rank for your brand. Do not negate SEO so quickly. The first page of the SERPs should be full of your site, your social profiles and a blog post or two praising your company with a positive review. So that any one searching for your brand can reaffirm that you're indeed purchase-worthy.
If you wish to try your hand at SEO - build review sites instead and rank them. Think of your store as Amazon, prepare proper authoritative review sites, presell your product and get sales.
