Yes ,it matters if you are focused to get banners on limited banner(Character banner or weapon banner). Always aim for 80 wishes for a guaranteed 5-star character. This is called pity system in GenshinImpact. Soft pity will start from 76th wish the chances of getting 5-star.
Look at the 76th wish most people get a 5 star there.
To conclude according to observations :
We should pull first 20 wishes as single wish ( rate becomes lower after 20th wish).If you are luck you will get 5-star in first 20 wishes.
Pull 10 wishes after 20–70 ( because rates are lower )
After 70th wish start pulling single wishes you are most likely to get 5-star at 76th wish most of then get it.
Doing this you can save primo gems for up-comming banners
