You'll still be eligible for benefits with £10,000 in savings, they'll just reduce your payments by £16 a week. The reduction is £1 per £250 over the threshold.
Be careful about trying to conceal the savings, because they can prosecute you for fraud. JobCentre staff are looking for any excuse, because they've got targets to meet.
If your parents gave you the money in cash, then I'd suggest just stashing it under the bed. If they made a bank transfer, I'd gradually withdraw the money in dribs and drabs rather than taking it out as one lump sum. Think up plausible excuses for spending the money in case you're challenged about it.
Taking it out in one go won't help; they'll say that you "deliberately deprived yourself of capital" and reduce your benefit as if you still had the money. The burden of proof is on you to show that you spent the money legitimately, not on the Jobcentre to show that you've hidden the money.
