Not Making Progress

Hello fellow language enthusiasts!

I'm learning Russian at the moment (although this applies to any language) and I'm at a point where all the words I see are just not used frequently and thus I see a word, translate it, try to make examples with it and then just forget it after a day or two bc I simply don't see it again for a long time. This is destroying my progress. I'm just translating these words over and over again. I just don't encounter these words often enough for me to remember them.

Will I just get past this at some point?

Any people who successfully learned a language to a high level, did you also struggle with this and how did you get past this? Thank you all in advance and have a great day!
