That is correct. I have never met anyone who was able to stop this behaviour without support from someone else whether that be from family or a support group or a professional like a doctor or a counsellor.
It may worry your parents. It will worry them more when you come up against the inevitable consequences of continuing to gamble – bankrupcy, homelessness, prison, possibly even suicide.
Get help now. Read through the posts in this forum to see what others have done and do the same. Loose access to money, access to gambling sites and find other things to do with your time. And beyond all else get the support you undoubtably need. I wish you well.
