every set is played till one of the two players gets 6 games first, but to win there must be a difference of atleast 2 games from the opponent so:

7-5, 6-4, 6-3, 6-2, 6-1 and 6-0 win

if both players are tied ate 6-6 then they go into a tiebreak where players play for single points, first one to 7 wins, again with a mandatory 2 point difference from the opponent, so it could be 7-5 or 20-18, in the tie break each player gets to serve in turn, two serves at a time per player

the reason the gametracker shows only one player serving constantly in the tiebreak is either a glitch or they are just too lazy to change it

now that you are still learning let me just tell you that womens tennis is way too unpredictable than mens tennis, you need a lot of studying or else you are just throwing your money away

mens tennis is simpler to handicap, more consistency in player performance
