Product snippets are 99.7% of my impressions. Is this an issue for e-commerce, I'm a little lost out here...

Hello all. I feel stupid asking this but stick with me. My wife has a little Shopify store. It doesn't make much money, so I've been doing my best to get her some exposure on Google. I've set up the pages to be structurally correct, added H tags in all the right places with rich product descriptions with all the right keywords, images, schema markup, created a GMC and GSC account with product feeds, etc. You name it; I've probably tried it. However, when I view the data in GSC, I see that the product snippets account for almost 100% of the impressions. Google says: >Product snippets: For product pages where people can't directly purchase the product. This markup has more options for specifying review information, like pros and cons on an editorial product review page. Merchant listings: These are pages where customers can purchase products from you. Given that this is a Shopify store intending to sell stuff (surface pages where customers can purchase products), it's a little concerning, as surely we would want merchant listing impressions more than product snippet impressions. Or am I reading this wrong? It's a competitive market, I get that, but I guess I'm wondering: 1. Does this matter? 2. If it does matter, what else can I do to improve merchant listing impressions? Like registering for GTINs, etc., Thanks for any help or advice.
