It is not impossible but it is a big gamble if you intended to make a living from the game, extra income is fine but as they say don't give up your day job.
You will have periods where you will have streaks of bad luck and won't be able to win a Dime, other times winning will be so easy you could be tempted to give up work for an easy lifestyle, but Poker is hard work and needs dedication to make money from it.
Even the professional Poker players study every week, I used to follow a Dutch player Lex Veldhuis on Twitch TV and he has a day off every week just to study the game, he is a professional player and have seen him play on "Late Night Poker" on TV against players like Doyle Brunson and Tony Gee.
The only advice I would give you is 2 words, Bankroll Management, study that before you start playing seriously.
