Does tours/shows sell ticket at the door?

It’s a tale as old as time, eplus/l-tike/pia are not overseas friendly unless you have a local number.

So I have some shows in mind that are NOT sold out (I check everyday on the various ticket platforms), what are the odds that they will sell the remaining seats/tickets at the door on the day of the show?
