Can I improve here something to make it more reponsive the good way

First you need to update the html. 

1. The picture element should be mobile first 
2. The stats should be an unordered list with 3 list items inside. No headings, that wouldn't make sense for numbers. Yoh can wrap the number/word in strong or span set to display block 

Then in CSS I'm afraid you need significant changes here
- always use a modern css reset at the start of the styles 
- font size must never ever be in px 
- never use 100vw 
- body 
- there should be no explicit heights or widths in this (only a height 100% on the image on larger screens)
- the component only needs a max width 
- on large screen only you can make the component a grid with 2 1fr columns or if a flex row the two children can be width 50%
