Just turning $1K into $10K in a year is easy, it's only 10 times the initial bankroll, I can even make it 50 - 100 times if given 1 year. Not only me, maybe some serious sports bettors here have the same thoughts as me.
However, behind that thought there is a big obstacle, which is consistency in betting choices, sometimes we feel that we are always lucky & have random without doing in-depth analysis. Easy to think, but not easy to do.
Are you so sure that it is so easy to do in a year? Then why don't you do it only with a larger amount, for example, not with 1k but with 10k, then in a year you will earn 100k (net profit will be 90k), which will be more than any average salary even in developed countries. It seems to me that this is too difficult a task, maybe there are players who can do it, but this may not always work out, and winnings will alternate with many losses. Even doubling a deposit is not easy, not to mention increasing it 10 times.
Making money from gambling it's not a certain income and turning 1k into 10k is also a very difficult task like you said so I doubt a regular gambler can make x10 with that bankroll but maybe some professionals gamblers could do it. However , I personally don't believe making easy money from gambling is real and those so called "professionals" gamblers cannot be fully trust that's for sure because even them can have bad calls and can easily lose your 1k$.
