Do 22lr barrels wear out?

22LR rifle can get worn out (other than by abuse) – the lead bullets are soft (even if “copper washed” and the steel bores are hard. Very different than using centerfire ammo with jacketed bullets. A million rounds doesn’t seem unreasonable to expect from a steel barrel using lead bullets.

Are heavy barrels more accurate?

They also do not heat up as quickly because of their greater mass. A hot barrel warps, which affects the point of impact of the bullet, i.e., accuracy. Lastly, a heavier barrel is literally heavier, which steadies the gun and cuts down on recoil, (assuming you’re shooting from a rest) which, yes, aids accuracy.
