Dispatched means your seller has sent your parcel.
This doesn't mean you will received it tomorrow, it just means it's "on it's way".
It depends what method postage your seller is using (will be stated on the listing).
If it's 2nd class, then you should receive within 2-3 working days from the time of dispatch (now).

It means your item has been posted or handed to the courier
It will give an estimated of delivery times on the transaction page depending on what service was used but you have to be patient as sometimes items take longer than other times.
I am sure your goods will arrive in good time but if they do not
Royal Mail do not deem items lost until 15 days.
Always contact your seller first if things do not arrive within a reasonable time

it means its been posted
nobody can say precisely when you will receive it the postal service isn't reliable to a day unless sent special delivery which is not guaranteed on saturday unless an extra fee is paid
it will likely arrive sometime early next week
