That's only tenuously true. They're mainly driven by earth's orientation, sure, but if that was all then you wouldn't get regional variations in seasons (like the wet & dry seasons some places get, rather than the 4 we get in most places).

It would also be impossible for winter to come early, and you ask any farmer they'll tell you that's a thing which happens

Seasons are more regional and varied than you might think

There are both astronomical and meteorological seasons.

Astronomical summer is June 21 to September 22. Meteorological summer is June July and August.

They also talk about winter sport season, breeding season and growing season. Everything is a season!
