I would like to know which font is this (https://fonts.gstatic.com/s/img/knowledge/glossary/terms/sty...) . I have tried to search but I am not sure how to actually find this info.

I'm doubting these are actual fonts. All we have is two characters made from SVG paths. The blue g is quite distinct, but whatthefont (https://www.myfonts.com/pages/whatthefont/) doesn't return a match. I think they were just illustrating the term.
