I think you can get away without learning grids, but flexbox is a must - given its convenience over the old “float-hacks” and its omnipresence in modern CSS. Besides the already mentioned css-tricks articles, I recommend checking out the guide to flexbox from mdn[1] (in the side menu there is also one for grids) as well as the reference to “CSS flexible box layout”[2]. These helped me get a deeper understanding about the concepts behind flexbox and how the properties and their shorthands actually work.
