help with ram usage

hey guys, 

so i have my HP laptop which is 1 year old, and i have been experiencing problems with ram.

I use my laptop mostly for surfing on internet, watching youtube, using ai, editting a video sometimes on premiere pro.

The problem is that my laptop is ALWAYS running on 50% on ram when i just sit on microsoft edge. i don't have alot of tabs open, i do't have multiple applications running etc.

i mostly use microsoft edge.

Is there anyway to fix this? 

i attached screenshots of the taskmanager. 

i have 1 tab open btw on crhome.
