Hello,
1. The “Browse categories” you can change directly via WoodMart -> Header builder -> Categories.

2. In general, these words are related to the theme, so we should create a translation in Loco Translate -> Themes (I already did it for you).
Also, I did one change to the “Search for products” field just to show you that everything works.
Define another text: https://prnt.sc/m_64APIDBzIO
Result: https://prnt.sc/HCbS2VY-FFSC
So try to change other text via Loco Translate -> Themes, and let me know if everything is sorted out.
Kind Regards
