You have to study hand ranges, positions in the table, study your opponents, there are several videos on YouTube, tournament or sits and go, also watching you learn.
Always listen to your 1st instinct if you think you have the better hand play it like you have the better hand but a lot of the game is luck and hoping you do have a better hand then the person your playing against
I'll watch videos and really understand the basic. Rules b4 playing but poker is a forever learning game.so my advice will be just play and keep playing to learn
