I highly recommend learning poker in the poker game application, Practicing directly is the best way to become proficient faster. in some applications, There is usually a feature explanation about the types of cards that make a win
or you can also try youtube because surely there is there who gives tutorials or lessons about poker
Practicing directly will cost you money though. It is good though because if you have something to lose while you play poker, you will do your best not to lose a dollar.
But there are poker browser extension that you can install which has play money to train yourself, there is no risk for it so you may still enjoy while you train to learn poker.
