Hi there udayantha11! You got a point in there. If a man with a bank account dies and no one withdraw his money in the bank until to the point the bank close his account, the money will go directly to the bank. In the case of bitcoin, when the bitcoin is stored in an online wallet and the wallet provider notice that the bitcoin is never been touch or no activity from the user for about so many year. I think the wallet company will acquire the bitcoins. And for the lesson, be sure that one of your family or relatives knew that you have bitcoins.
