how can i know if my metadescription will show up on Google

how can i know if my metadescription will show up on Google ?

I create different metadescriptions for different game descriptions

The descriptions are not articles, this is like a product description

What I did:

I was checked the results from phrases that I interest, and checked the sites that appear on the search results

And found some of the repeated words appear there.

Im not sure if that works for all, but is what I think will do
