yup friction is self adjusting as if there is any force in any body , then it come and opposes the force always .

we can also say if the body has 1 N force then there is also 1 N friction force.
but it value is limited

yes it is true that friction itself is an existing force actually what happens is that there are two types of fractions mainly when is static friction and one is limiting static friction static friction is when the object is at rest and limiting friction is the maximum friction up to which one object can oppose the impact of applied force because if we apply a force which is slightly more than the limiting static friction than the object will move so let's understand by the help of an example let's suppose you have a box which have a limiting static friction of 20 Newtons now suppose you apply a force of 5 Newton on that box and it does not move now if you think normally then you will say that frictional force which is acting in opposite direction to applied force is 20 Newtons but applied force is 5 Newtons so you will say that frictional force is more than the applied force subject should move in direction of frictional force which is not possible so that's why we say that the friction here is not the limiting static friction it is the only static friction that means when we apply a force of 5 Newton then box also apply frictional force of 5 Newton in opposite direction so that both forces become balance and the body should not move similarly if we apply force of 15 Newton then also the box will apply equal and opposite frictional force that is the box will provide 15 Newtons of frictional force but if we apply a force of 21 Newtons then the box will not be able to provide 21 Newton frictional force because its limiting value is 20 Newtons only so the boxing more so we have concluded That Till the limiting value is reached friction force can adjust itself according to the applied force hands its prove that fictional Force is a self adjusting force
