3Gb Ram memory never goes higher than 1,9gb, is this normal?

[jogros]

Hi, I have the moto e4plus 3gb version, but I´ve noticed that even opening all apps I have, a few heavy games, office tools and others, Ram memory usage never goes higher than 1,9gb, is this OK? I have the feeling my phone has 3gb but the OS or software is just treating it like a 2gb phone
Anyone knows if this is normal?

thank
